LNK403EG Datasheet (Power Integrations)

LNK403EG, LED Driver IC

The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring PF >0.9, TRIAC dimmer capability and high efficiency.

The single-stage PF and constant current controller eliminates passive circuitry required for power factor correction and electrolytic bulk capacitor.
