Primary-Side Regulated Flyback for Universal AC Input and 15V/0.25A Output Reference Design

Overview

TopologyFlyback Converter
Input voltage90-265 V
Output 115 V / 0.25 A
IC revisionA

Description

The PMP9171 reference design uses the UCC28910 primary-side regulated flyback controller with integrated MOSFET to generate a 15V/0.25A output from an univeral AC input with safety isolation rated transformer. 80% efficiency is achieved at full load and less than 130mW power consumption is observed during no load condition.
