DESCRIPTION
The PD-NPM-0305EP module is a wide range input voltage DC/DC converter. The module employs advanced power topology that enables high efficiency, a wide input range and compact size. It is especially designed to work as the remote (NTU) power module in remotely fed HDSL systems. The module has a shutdown mode, which when activated ("High" level on Inhibit pin), reduces the input current to sleep-mode level of approximately 1mA. The module is designed to perform optimally while working in conjunction with PowerDsine PD-LPM-0xxx module series, but may also be used in a wide range of other DC/DC applications. One of the PD-NPM-0305EP's most valuable features is its ability to work with input voltages as low as 36Vdc. This feature enables the use of the module in systems, which are locally powered from a TNV 48Vdc line. In these cases, there is no need to use any additional DC/DC converters for logic circuits supply power, thereby reducing system costs and complexity. The PD-NPM-0305EP offers enhanced efficiency and an extended temperature range, commonly required for HDSL/xDSL repeater applications. The Module also includes an adjustable output voltage range of 100mV and features a plastic cover thereby reducing unit weight. Reducing the Module's output voltage level by a few mVolts may reduce the logic circuits and overall RT modem's power consumption.

Connecting a resistor, RADJ, between Pin 5 and Pin 1 will increase the output voltage of Output 1and Output 2. Connecting a resistor, RADJ, between Pin 5 and Pin 2 6.25 will decrease the output voltage of Output 1and Output 2. Vout = Vout - Typical 51 + RADJ(K) 2. Output currents below the minimum rate may cause total regulation to divert from rated specifications. In cases where Output 1 or Output 2 is not in use, the unused output should be loaded for minimal current consumption with a resistor. 3. The unit is designed to meet EN55022 Class B Standard with an external EMI filter. For filter design recommendations, refer to the PowerDsine xDSL Power Modules Application Note. 4. In order to comply with the EN60950 standard in telecommunication networks, the unit's input voltage must not exceed 120Vdc. 5. In order to comply with the EN60950 standard, the maximum operating ambient temperature must be 85C. 6. Output ripple may reach 150mV at ambient temperatures below -10C. 7. When the Inhibit function is not used it is recommended to permanently connect the Inhibit terminal to Vin RTN (pin 8).

Typically feeds from the line through bridge rectifier to prohibit voltage reversal. Logic input, relative to Vin RTN (pin 8) with an internal pull down resistor. High logic level will inhibit operation of the module, and the device's current consumption will drop to an idle level. Leaving this pin unconnected, or connecting it to a low logic level, will enable the outputs. When the Inhibit function is not used it is recommended to permanently connect the Inhibit terminal to Vin RTN (pin 8). Negative supply terminal pin. Typically feeds from the line through the bridge rectifier prohibit voltage reversal.
