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-0305EPs 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.
