Description
The PIM300X-series is the higher power version of its highly successful predecessor, the PIM200X series. Besides providing higher power over extended temperature range, the module is pin compatible and retains the same form factor as the PIM200X series for ease of upgrading to higher power or thermally challenging ATCA board designs. The PIM200X/300X series are a new class of power modules designed to greatly simplify the task of implementing dual redundant, hot swap -48Vdc power distribution with EMI filtering on an ATCA or other telecom boards. The PIM300X, when used with a variety of Lineage Power's dc-dc converters/POLs provides for a quick, simple and elegant power architecture solution to a wide variety of complex power requirements. While providing high reliability, innovative features and compact design at a low cost, the module significantly reduces the valuable telecom board real estate compared to conventional discrete designs. Besides processing the main -48V bus, the module greatly simplifies the task of powering the IPM (for ATCA applications), system management or other housekeeping functions by providing a completely isolated auxiliary 3.3V or 5.0V power bus.

CAUTION: This power module is not internally fused. Both A & B feeds and their corresponding returns must be individually fused.
To preserve maximum flexibility, internal fusing is not included. However, to achieve maximum safety and system protection, the safety agencies require a fast-acting fuse with a maximum rating of 15 Amps and Voltage Rating >/= 75Vdc for the -48AF, -48BF VRTN_AF & VRTN_BF feeds. Consult Fusing and fault protection (Section 4.1.4) of PICMG 3.0 ATCA specifications for additional information. Based on the information provided in this data sheet on inrush current and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data sheet for further information.

Introduction
PIM300X Series; ATCA Board Power Input Modules -38 to -75Vdc; 300W Input
& ENABLE_B. The ATCA backplane connects the ENABLE_A to VRTN_A, ENABLE_B to VRTN_B, EARLY_A to -48V_A and EARLY_B to -48V_B. Optional EARLY_A & EARLY_B Connections: During hot insertion of the ATCA board, the Inrush Control circuit limits the surge current to the C_FLTR capacitor. However, due to the presence of internal EMI filter capacitance (located before the Inrush Control circuit), there is a possibility of a surge current that results in a voltage sag for 5 to 10 microseconds. In most cases this should not be of concern because all the ATCA Boards and FRU's on the -48V bus should be able to ride thru a 5msec/0Volt transient event per the PICMG 3.0 specifications. In case this is undesirable, it is recommended that Precharge resistors, R1 & R2 (15 Ohms, with high surge capability) should be connected as shown in the Typical Application circuit.
The PIM300X module is designed to support the Advanced Telecommunications Computing Architecture (ATCA) power entry distribution requirements for the Front Board / Blade per the PICMG 3.0 specifications. The PICMG 3.0 specification defines the Mechanical, Shelf Management Interface, Power Distribution, Thermal, Data I/O and Regulatory requirements for the next generation of modular telecom architecture platform for use in Central Office telecom environments.
Input Pin Connections
The ATCA board is specified to accept up to a maximum of 300W of input power via dual, redundant -48Vdc Feeds through the Zone 1 (Power and Management) connector, designated P10. The power connector provides board to backplane engagement via pins of varying lengths. Please consult the PICMG 3.0 specifications for details. The following are the design considerations of the input pin connections of the PIM300X to the ATCA power connector.

* Optional The first pins to mate in the ATCA power connector are the EARLY_A, EARLY_B, the two grounds (LOGIC_GND, SHELF_GND) and the two returns (VRTN_A, VRTN_B); followed by staggered connections of -48V_A and -48V_B power Feeds. The last pins to engage are the two short pins, ENABLE_A
Notes: (1) -48V Main Output Bus: (Signal Names: -48V_OUT & VRTN_OUT) This is the main -48V output bus that provides the payload power to the downstream (one or more) DC/DC converters. The PIM300X module does not regulate or provide isolation from the input -48V A/B feeds. The main functionality of the module is to provide 48V A/B Feeds OR'ing, inrush protection for hot swap capability and EMI filtering to attenuate the noise generated by the downstream DC/DC converters. * The -48V_OUT pin connects to the Vin(-) pin and the VRTN_OUT pin connects to the Vin(+) pin of the DC/DC converter(s).

* The -48V_OUT bus may require a fuse depending on the power and fusing requirements of the DC/DC converter.
PIM300X Series; ATCA Board Power Input Modules -38 to -75Vdc; 300W Input
For 300W and 9.3 ms holdup requirements, this results in a 2.9 Kohm resistor with 1W rating. Worst case power dissipation of R_Bleed (=2.9Kohms) @ -36V is 0.45W. * The R_Bleed is connected across the 72V_CAP and VRTN_OUT pins of the PIM300X.
*
Input filtering of the DC/DC converter is provided by C_FLTR close to the input pins of the DC/DC converter(s); additional high frequency decoupling ceramic capacitors (0.01 to 0.1F are recommended for improved EMI performance. The maximum C_FLTR capacitance across all the downstream DC/DC converters should not exceed 330F. The recommended capacitor voltage rating should be >/= 100Vdc. The minimum C_FLTR capacitance (200F) recommendation is based on meeting the EMI requirements. Based on end systems test, the capacitance may be lowered if real estate is an issue. As a minimum, 50 F to 100 F is strongly recommended to stabilize the line impedance for proper startup of the DC/DC converter. Refer to the DC/DC converter's data sheet for the recommended capacitor.

(3) Management Power (MGMT_PWR) The MGMT_PWR output is an isolated secondary voltage (3.3V for PIM300F or 5.0V for PIM300A) referenced to LOGIC_GND that provides 8W(maximum) power to the IPM Controller for the ATCA board or to the power up system controller for other applications. * Per PICMG 3.0 Specs, the ATCA board shall not consume more than 10W of input power; this includes the standby power of PIM300X (typically 1.7W) as well as all the on board DC/DC power converters. It is the responsibility of the board designer to insure that this requirement is met prior to power-up rights have been negotiated with the Shelf Manager. The management power is available even when the input voltage is down to -36Vdc. No additional output capacitors are required, but a 22F tantalum/ceramic and a 0.01 to 0.1F ceramic capacitors are highly recommended to contain the switching ripple and noise.
(2) Holdup / Bulk Capacitor Output (72V_CAP) This output provides the high voltage (nominal 72Vdc) to charge the C_BULK capacitor(s) to allow the ATCA board to meet the 5ms, 0Volts transient requirements. * The 72V_CAP connects to the +ve terminals of the C_HLDP capacitors while the -ve terminals of the C_HLDP connects to the 48V_OUT bus. Since the 72V_CAP output is regulated to 72Vdc (+3%/-5%) and the capacitors are off line during normal operation, the capacitors may be selected with voltage rating of >/= 80V to minimize the real estate on the board. The C_HLDP capacitance is dependent on the system power and the holdup time requirements based on the following formula Bleed Resistor (R_Bleed) : The PICMG 3.0 specifications requires a discharge mechanism (e.g. bleed resistor) to discharge the holdup/bulk capacitance to less than 60Vdc and less than 20 joules within one second of disconnection from the backplane. This requirement is fulfilled by installing R_Bleed resistor that is selected based on the C_HLDP selected in the previous step. The formula for selecting the resistor is :
* *
*
*
C _ HLDP( F ) [ Pout (W ) {Tholdup(ms) + 1.7}] / 1.9
*
Higher output capacitance may be required in case of large input line or output load transient conditions. (4) -48V Feed Loss or Open Fuse Alarm (-48V_ALARM) The -48V_ALARM output is an opto-isolated signal internally referenced to the LOGIC_GND. The signal is an open collector output that requires an external pull up resistor. A 3.3K pull up resistor to 3.3V, MGMT_PWR (for PIM300F) should suffice. During normal operation, the signal is LO (opto conducting). During fault condition, the opto shall stop conducting and the alarm signal shall assume a HI state.
*
Safety Considerations
For the system safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12 (EN60950-1) Licensed.

PIM300X Series; ATCA Board Power Input Modules -38 to -75Vdc; 300W Input
The power input to these units is to be provided with a maximum of 15 Amps fuses with a voltage rating of at least 75Vdc. Refer to "Thermal Consideration" section for additional safety considerations.
Feature Description
A/B Feed OR'ing
The module provides dedicated OR'ing functionality to both Feeds A & B and their corresponding returns. The following pairs of signals are OR'd within the module: -48V_AF / -48_BF, VRTN_AF / VRTN_BF, and ENABLE_AF/ ENABLE_B. The -48V A/B feeds and their corresponding returns are OR'd via N-channel MOSFET power devices resulting in a highly efficient system compared to conventional diode OR'ing scheme.
Figure 17. Typical Class B EMC signature of PIM300F with QBW025A0B1 module. For Safety and noise considerations, copper traces must not be routed directly beneath the power module (PWB top layer). C_EMI capacitors must make direct connections (preferably without vias) to the DC/DC module pins with as much copper width as possible. In case vias are necessary, allow for multiple connections to the inner plane with vias placed outside the footprint of the module. For additional layout guide-lines, refer to Lineage Power's FLT007A0 Input Filter Module data sheet.
EMI Filtering
The module incorporates an EMI filter that is designed for the ATCA board to help meet the conducted emissions requirements of CISPR 22 Class B when used in conjunction with Lineage Power DC/DC converters approved for ATCA applications. The following insertion loss table is provided as filter performance guidelines. Parameter Common-Mode Insertion Loss 50 Ohms circuit, 200kHz 50 Ohms circuit, 500kHz 50 Ohms circuit, 1MHz Differential-mode Insertion Loss 50 Ohms circuit, 200kHz 50 Ohms circuit, 500kHz 50 Ohms circuit, 1MHz 75 66 61 dB dB dB 24 32 39 dB dB dB Typical Unit
Inrush Current Control / Hot Plug Functionality
The module provides inrush current control / hot plug capability. The peak value of the inrush current and the duration complies with the PICMG 3.0's Inrush Transient specifications. The specifications shall be met with the external C_HLDP and C_FLTR capacitances as specified in the previous sections. The unique design of the module where the large energy storage capacitors are segregated from the input filter capacitors allows the module to meet the stringent PICMG's inrush transient specifications. In conventional designs where the energy storage capacitors and the filter capacitors are in parallel, it is extremely difficult to meet the inrush transient specifications without over sizing the inrush control power FET.
The following Figure 17 depicts the Class B EMI performance of PIM300F when tested with QBW025A0B1 on a stand alone basis (ATCA form factor load board with resistive loads and only power, return and chassis connections to the backplane). The external filtering components are identified in the Typical Application circuit.
A/B Feed / Fuse Alarm (-48V_ALARM)
The module monitors the A & B feeds as well as the status of the A&B feed fuses and provides an optoisolated signal in case of loss of a feed or the opening of any of the fuses. The response time of the fault condition is < 100 sec. The alarm signal indicates normal operation when the opto coupler transistor is conducting and a fault condition by an off state.

Holdup Capacitor Charging Current (72V_CAP)

internal current-limiting circuitry. The unit can endure current overload conditions continuously or shutdown due to thermal protection depending on operating ambient temperature conditions. The unit will restart automatically once the overload condition is removed.
The module employs a unique feature to charge and recharge the external energy storage holdup/bulk capacitors (C_HLDP) within seconds from the application of power to a nominal voltage of 72Vdc (+3%/-5%) resulting in significant reduction in the real estate on the board in order to comply with the PICMG 3.0's 0 volt/5msec transient requirements. Since the 72V_CAP is also regulated, there is further reduction in real estate board because now 80V capacitors with higher capacitance can be used instead of the >/= 100Vdc caps required in conventional designs. The maximum rate of input voltage change (dv/dt) shall not exceed 5V/ms when the -72V_CAP output is switched on the 48V_OUT/VRTN_OUT bus. The holdup capacitors are switched on automatically when there is a loss of power on both feeds A & B or both feeds have dropped below -38V (typical). Upon restoration of normal power on either or both feeds, the holdup capacitors automatically go off line and are recharged for the next power loss event. Note 1: The holdup capacitors and the bleed resistor are installed external to the module. Note 2: The PICMG 3.0's requirements for the 0 Vdc transient for 5ms is normally interpreted as the holdup time requirement by many. In actuality, when one considers the additional specification of 50V/ms fall time and 12.5 V/ms rise time to and from the 0Vdc condition, this leads to a 9.3ms of total hold up time requirement when power is interrupted at -43Vdc. The 72V_CAP output provided by the module to charge the bulk capacitors provides a tremendous advantage over conventional designs in terms of real estate requirements on the board with the added benefit of the usage of 80V capacitor rating vs >/=100V. The holdup time, Tholdup, is defined for power loss at 43Vdc input and the C_HLDP maintaining -48V_OUT bus to at least -36Vdc (which is the minimum operating voltage of the downstream DC/DC bus converter). Note 3: Bleed Resistor (R_Bleed): Normally, the bleed resistor is not required as there is sufficient standby current drain within the module to bleed the holdup capacitors from 75V to 60V in 1 second as specified in the PICMG 3.0. Again, due to the PIM300X's unique design, the placement of the bleed resistor results in significantly less power dissipation compared with conventional designs where the bleed resistor is sized for -75Vdc continuous maximum voltage and -100V transients.
Input Under Voltage Lockout
At input voltages below the input under voltage lockout threshold limit (VUVLO), the module operation is disabled. The module will begin to operate at an input voltage above the under voltage lockout turn-on threshold(VUVHI). Please see the Electrical Specifications Table for the specified trip points.
Transient Over Voltage Protection
The module incorporates a Transient Voltage Suppressor. This feature helps protect the module and the downstream DC/DC converters from input voltage transients exceeding -75Vdc. The TVS is rated for 1500W of Peak Pulse Power with the Breakdown Voltage (VBR) of 77.8V to 86.0V.
Input Reverse Polarity Protection
The module shall not be damaged from reverse polarity connection in the event of miswiring of either input feeds at the shelf input terminals.
Over Temperature Protection
To provide over temperature protection in a fault condition, the unit will shutdown if any thermal sensor reference point TOTP (identified in Figure 16), exceeds o o the trip point of 125 C (+/- 5 C). The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restart after it cools down. During thermal design verification, it is recommended that these temperatures be monitored by IR Thermal imaging camera. In case thermocouples are used, the thermocouple contacts should be attached as close as possible to the thermal sensors (thermistors) on the PWB but not directly on the thermistors themselves. Attaching the contacts directly to the thermocouple is not recommended as this will result in false temperature measurements due to the heat sink effect of the thermocouple wires.
Management Power (MGMT_PWR) * * *
The module provides up to 8W of 3.3V (PIM300F) or 5.0V (PIM300A) of isolated output power referred to LOGIC_GND. The management power is available automatically as soon as the input voltage levels are within -36Vdc to -75Vdc. The output is short circuit and over voltage protected with low ripple and noise.
Over Current Protection (- 48V_OUT Bus)
To provide protection in a fault (output overload or short circuit) condition, the unit is equipped with

Power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel.

Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Lineage Power's Electronics Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS)

Figure 18. Thermal Test Set-up
The thermal derating curves were generated with the airflow parallel to the long axis of the module (input to output). The thermal reference points, Tref 1 to Tref 3 are identified in Figure 15. For reliable operation and to comply with the module's safety requirements, these temperatures should not exceed the limits specified in the figure. Exceeding these temperatures may or may not trigger the over temperature shutdown. The output power of the module should not exceed the rated input power of the module i.e. 300W. Please refer to the Application Note "Thermal Characterization Process For Open-Frame BoardMounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures.
