Introduction

This document is an engineering report describing a 230 VAC input, 5-output flyback

supply utilizing

TOPSwitch®-GX (TOP246Y). The supply is rated for 43 W continuous

output power, with 57 W of peak power capability for starting a disk drive. The design is

optimized for high-end set-top box applications, but is easily adapted for other multiple

output uses such as VCRs, DVD players, cable modems, and direct satellite receivers.

The design kit includes a component kit and instructions for converting the supply to

115 VAC input operation.

This document contains the power supply specification, schematic, and bill of materials,

transformer documentation, printed circuit layout, and performance data.
