EPR-000013 – 43 W Multiple Output TOP246 Power Supply
08-May-2001
1 Introduction
This document is an engineering report describing a 230 V_AC 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 V_AC input operation.
This document contains the power supply specification, schematic, and bill of materials,
transformer documentation, printed circuit layout, and performance data.
