80V/50W Upside-Down Buck Reference Design

Overview

TopologyBuck Converter
Input voltage85-265 V
Output 180 V / 0.62 A
IC revisionB

Description

This UCC28730 based upside-down buck design converts a universal line input to a non-isolated 80V/50W output. An additional 12V/600mW output is produced using a UCC28880. The design achieves over 93% efficiency and consumes less than 50mW of standby power.
