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.
