DER-141: 5V @ 150mA, 85 ~ 265VAC in

Summary

This engineering report describes a power supply design which utilizes the LinkSwitch-XT device LNK363DN. This power supply is ideal for use in tamper-resistant energy meters. The transformer uses a powdered-iron core, which makes core saturation, and therefore supply failure by external magnetic influence, much less likely.

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