Reference Designs

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.
