Texas Instruments UCC28700 | Demoboard PMP30428

Overview

TopologyFlyback Converter
Input voltage85-400 V
Output 112 V / 1.1 A

Description

85-VAC - 400-VAC input multiple output flyback reference designThis offline flyback reference design uses the UCC28700 controller to generate 2 isolated outputs (12 V at 1.2 A, -3.3 V at 10 mA) from an AC input (85 VAC - 400 VAC). The controller provides accurate voltage and current regulation with primary-side feedback, eliminating the need for opto-coupler feedback circuits. The valley-switching technique reduces switching losses and keeps the efficiency high.

Features
