PMP9018

Primary-Side Regulated Flyback with 85-277VAC Input (24V @ 0.5A) Reference Design

PMP9018

Design files

Overview

The PMP9018 reference design uses the UCC28700 primary-side regulated flyback controller to generate a 24V/0.5A output from an 85V-277V AC input. The valley switching of the UCC28700 allows this low-cost design to achieve efficiencies over 87%; no load losses are less than 50mW.
