LNK403 Datasheet (Power Integrations) - LinkSwitch-PH LED Driver IC

LNK403, LinkSwitch-PH LED Driver IC

The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability (LNK403-409).

The single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacito
