DER-302: 200mA @ 36V Max, 185 ~ 265VAC in

Summary

The document describes a non-isolated, high-efficiency, high power factor (PF), TRIAC dimmable LED driver designed to drive a nominal LED string voltage of 36 V at 200 mA from an input voltage range of 185 VAC to 265 VAC (47 Hz – 65 Hz). The LED driver utilizes the LNK460VG from the LinkSwitch-PL family of ICs.

The topology used is a single-stage non-isolated buck that meets the stringent space and efficiency requirements for this design.

LinkSwitch-PL based designs provide a high power factor (>0.9) meeting international requirements.

This document contains the LED driver specification, schematic, PCB details, bill of materials, transformer documentation and typical performance characteristics.
