The document contains the power supply specification, schematic, bill of materials, printed circuit layout and performance data. The output is non-isolated and requires the mechanical design of the enclosure to isolate the output of the supply and the LED load from the user. The form factor of the board was chosen to meet the space limitations of standard Candelabra LED replacement lamps. LinkSwitch-PL based designs provide a high power factor (>0.91) meeting current international requirements. The board was optimized to operate over the high AC input voltage range (190 VAC to 265 VAC, 47 Hz to 63 Hz).

The key design goals were high efficiency, dimmable and compact size, enabling the driver to fit into candelabra and B10 sized lamps and maximize efficacy. The DER-301 provides a single constant current output with an output power of 3.8 W output. This document is an engineering report describing a non-isolated dimmable LED driver (power supply) utilizing a LNK457DG from the LinkSwitch-PL family of devices.
