EPR-32 - 25 W Multiple Output TOP245P Supply
1 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.
