LNK418 - 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 (LNK403-410).
The single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacit
