DER-303: 200mA @ 36V Max, 185 ~ 265 VAC

The document describes a non-isolated, high efficiency, high power factor (PF) 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 – 63 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 design was not optimized for operation with phase dimmers. If this is a requirement, please see DER-302.
