Description

This application report reviews the design steps used in the evaluation module (EVM) UCC25230EVM-754. The EVM helps evaluate the UCC25230 pulse-width modulation (PWM) controller in a forwardflyback or Flybuck™ dc-dc converter topology for a 48-V telecom bias supply. The EVM is a dual-output converter with 1500-VDC isolation between the two outputs. Each output is typically rated as 12 V and 65 m
