High power led driver circuit using LNK403EG

This high power led driver circuit is designed using LNK403EG IC designed by Power Integrations which can drive an LED string of 18 V at a current of 0.38 A (both nominal) from an input voltage range of 90 VAC to 265 VAC.
The topology used in this high power led driver circuit is an isolated flyback operating in continuous conduction mode.

Power LED driver circuit using ISL97672A

This power led driver circuit is designed using the ISL97672A controls six channels of LED current for LCD backlight applications. The ISL97672A power LED driver is capable of driving LEDs from 4.5V to 26.5V, with a maximum output of 45V.
The ISL97672A power LED driver employs an adaptive boost switching architecture that allows Direct PWM dimming with linearity as low as 0.007% at 200Hz or 0.8% at 20kHz. Dimming can be as high as 30kHz.
