Lighting > LED Drivers - AC / Offline DER-288: 500mA @ 33V Max, 90 ~ 265VAC in Manufacturer: Power Integrations

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.

Lighting > LED Drivers - AC / Offline DER-281: 500mA @ 33V Max, 180 ~ 265VAC in Manufacturer: Power Integrations

The document describes a high power factor (PF) TRIAC dimmable LED driver designed to drive a nominal LED string voltage of 30 V at 0.5 A from an input voltage range of 180 VAC to 265 VAC. The LED driver utilizes the LNK405EG from the LinkSwitch-PH family of ICs.
