Description

PMP8878 is a full-function 1/8th brick isolated DC/DC telecom power module based on UCC28250 advanced PWM 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 40V-75V input source. The highlights of the reference design include 95% peak efficiency, pre-bias start-up, overtemperature protection and overcurrent protection (hiccup mode). The bias supply block employs the UCC25230, while the gate drivers used in this design include UCC27324 for driving the SR MOSFETs and UCC27201 for driving the primary side Half-Bridge MOSFETs.
