DER-106: 24V @ 625mA, 90 ~ 265VAC in

Summary

This document is an engineering report describing the design of an AC-DC power supply with universal input providing a regulated +24 VDC at 625 mA. The design, rated for 15 W is implemented using a TOP244P device from the TOPSwitch-GX IC family and an EEL19 core in a Flyback topology. This power supply is intended to be used in a refrigerator appliance where the maximum ambient temperature can reach 70°C.

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