Texas Instruments UCC28780 | Demoboard PMP30631 | Würth Elektronik Reference Design Search

Overview

Topology	Flyback Converter
Input voltage	90-264 V
IC revision	B

Description

This reference design uses the UCC28780 active clamp flyback controller to generate an isolated output of 20 V @ 3.5 A over an input voltage rage of 90 Vac to 264 Vac. The design also uses the UCC24612 synchronous rectifier controller on the secondary side. Zero voltage switching (ZVS) ensures high efficiency over a wide operating range.

Features

Zero voltage switching (ZVS) provides high efficiency (93% peak value)
Adaptive burst mode feature maintains high efficiency even at light loads
Synchronous rectifier using drain-to-source voltage sensing
