PMP8877, 1/8th Brick Isolated DC/DC Telecom Power Module based on UCD3138 Digital Controller

PMP8877, is a full-function 1/8th brick isolated DC/DC telecom power module based on the UCD3138 digital power controller. The reference design features secondary side control and hard switching full bridge power topology to deliver 12V/180W of output power operating across a wide range 36V-72V input source. The highlights of the reference design include 94% peak efficiency, fast input voltage feedforward response to input voltage surges, constant current/constant power overload protection, pre-bias start-up, current sharing control for paralleled module applications and PMBUs support for communication with peer controllers
