Texas Instruments UCC28780 | Demoboard PMP30631

Overview

TopologyFlyback Converter
Input voltage90-264 V
IC revisionB

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
