1/8 Brick Isolated DC/DC Telecom Power Module Based on UCD3138 Digital Control Reference Design (PMP8877)

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. The bias supply block employs the UCC25230, while the gate drivers used in this design include UCC27524 for driving the SR MOSFETs and UCC27211 for driving the primary side Half-Bridge MOSFETs. Other components include the ISO7240 for sending signals across the isolation barrier.
