5.2W Primary-Side Regulated Flyback With 108V to 305V AC Input Reference Design

Overview

TopologyFlyback Converter
Input voltage108-305 V
Switching frequency115 kHz
Output 118 V / 0.25 A
Output 218 V / 0.04 A
IC revisionB

Description

The PMP30198 reference design uses the UCC28910 flyback controller with integrated MOSFET to generate two isolated outputs (18V@0.25A / 18V@0.04A) from an AC input. The UCC28910 implements primary-side regulation, eliminating the need for an opto-coupler and reducing the total component count.
