feature (<50 m W at 230 VAC) Accurate and Consistent Performance - pensates for transformer inductance variations - pensates for line input voltage variation - Frequency jittering greatly reduces EMI filter size and cost Advanced Protection and Safety Features - Auto-restart for short-circuit protection - Open circuit fault detection mode - Automatic thermal shutdown restart with hysteresis - Meets high voltage creepage requirement between DRAIN and all other signal pins both on PCB and at package Green Package - Halogen free and ROHS pliant package Applications - Off-line LED driver Description The Link Switch™-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability (LNK403-410). The single-stage bined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacitor. The advanced primary-side control used by the Link Switch-PH device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits.
