DAK-32: 20W, 3.3V, 5V, 12V, -24V, 85 ~ 265VAC

Summary

Design Accelerator Kits (DAK) provide all of the essential materials to get you started on your next switch mode power supply design. The kits include a fully assembled and tested prototype power supply board, comprehensive engineering report, product samples, unpopulated circuit board, data sheet and other related documentation.

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.

The document contains the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout, and performance data.
