Introduction

This document is an engineering report describing the design of an AC-DC power supply

with universal input and 4 outputs. The design, rated for 20 W (25 W peak), is

implemented using a TOP245P device from the TOPSwitch-GX IC family and an EEL25

core in a flyback topology.

The document contains the power supply specification, schematic, bill of materials,

transformer documentation, printed circuit layout, and performance data.
