DER-288: 500mA @ 33V Max, 90 ~ 265VAC in

Summary

This document describes an isolated, power factor corrected, very high efficiency LED driver (non-dimmable) designed to drive an LED string of 30 V at a current of 500 mA (both nominal) from an input voltage range of 90 to 265 VAC. The design employs an active ripple filter to achieve less than 30% output ripple. A reference board DER-284 was used with active ripple filter daughter board.

The LED driver uses a LNK417EG device from the LinkSwitch-PH family of ICs. This integrated controller and 725 V MOSFET dramatically reduces the complexity and component count of the solution.

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