| 12 Vin single output DC-DC CONVERTERS POLA Non-isolated NEW Product 1 * 6 A output current * 12 V input voltage * Wide-output voltage adjust * 1.2 Vdc to 5.5 Vdc for suffix `W' and 0.8 Vdc to 1.8 Vdc for suffix `L' * Auto-trackTM sequencing* * Efficiencies up to 93% * Output ON/OFF inhibit * Output voltage sense * Point-of-Load-Alliance (POLA) compatible * Available RoHS compliant The PTH12050 is a next generation series of non-isolated dc-dc converters offering some of the most advanced POL features available in the industry. The primary new feature provides for sequencing between multiple modules, a function, which is becoming a necessity for powering advanced silicon including DSP's, FPGA's and ASIC's requiring controlled power-up and power-down Other industry leading features include efficiencies up to 93%. The PTH12050 has an input voltage of 10.8 Vdc to 13.2 Vdc and offers a wide output voltage range adjustable with external trim resistor, allowing for maximum design flexibility and a pathway for future upgrades. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 C unless otherwise stated Cin = 100 F, Cout = 0 F OUTPUT SPECIFICATIONS Voltage adjustability (See Note 4) Setpoint accuracy Line regulation Load regulation Total regulation Minimum load Ripple and noise 20 MHz bandwidth Suffix `W' Suffix `L' Vo Vo Vo Vo 2.5 V > 2.5 V 1.0 V > 1.0 V Suffix `W' Suffix `L' 1.2-5.5 Vdc 0.8-1.8 Vdc 2.0% Vo 5 mV typ. 5 mV typ. 3.0% Vo 0A 25 mV pk-pk 1% Vo 20 mV pk-pk 30 mV pk-pk 0.5% Vo EMC CHARACTERISTICS Electrostatic discharge Conducted immunity Radiated immunity EN61000-4-2, IEC801-2 EN61000-4-6 EN61000-4-3 PTH12050 SPECIFICATIONS GENERAL SPECIFICATIONS Efficiency Insulation voltage Switching frequency Over Vin and Io ranges Approvals and standards Material flammability Dimensions Weight MTBF Telcordia SR-332 (L x W x H) Suffix `W' Suffix `L' See Tables on Page 2 Non-isolated 320 kHz typ. 250 kHz typ.

L = Low Voltage Product Family Point of Load Alliance Compatible Input Voltage 12 = 12 V Output Current 05 = 6 A Mechanical Package Always 0 Output Voltage Adjustment of the PTH12050 Series The ultra-wide output voltage trim range offers major advantages to users who select the PTH12050. It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 1.2 V to 5.5 V for suffix `-W' and 0.8 V to 1.8 V for suffix `-L'. When the PTH12050 converter leaves the factory the output has been adjusted to the default voltage of 1.2 V for the PTH12050W and 0.8V for the PTH12050L. Notes Remote ON/OFF. Positive Logic ON: Pin 3 open; or V > Vin - 0.5 V OFF: Pin 3 GND; or V < 0.8 V (min - 0.2 V). 2 See Figure 1 for safe operating curve. 3 A 100 F electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 750 mA rms of ripple current. C2 = 10 F ceramic capacitor, required for output voltages of 3.3 V and higher. 4 An external output capacitor is not required for basic operation. Adding 100 F of distributed capacitance at the load will improve the transient response. 5 1 A/s load step, 50 to 100% Iomax, Cout = 100 F. 6 If utilized Vout will track applied voltage by 0.3 V (up to Vo set point). 7 Tape and reel packaging only available on the surface-mount versions. 8 The pk-pk output ripple voltage is measured with an external 10F ceramic capacitor. See Figure 3 Standard application schematic. 9 To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option `S' with `Z', e.g. PTH12050WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option `H' with `D', e.g. PTH12050WAD. 10 NOTICE: Some models do not support all options.
