Texas Instruments UCC28633 | Demoboard PMP30092.1

160W Primary-Side Regulated Flyback Using UCC28633 Reference Design

Overview

TopologyFlyback Converter
Input voltage85-264 V
Switching frequency1-120 kHz
Output 127 V / 6 A
IC revisionB

Description

The PMP30092 reference design uses the UCC28633 high power flyback converter to generate an isolated output (27V @ 6A). The UCC28633 operates in both CCM (continuous conduction mode) and DCM (discontinuous conduction mode). Primary side regulation eliminates the need for an opto-coupler and reduces the total component count. The secondary side wake-up controller UCC24650 enables excellent load transient performance and low standby power.
