The LNK419EG 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 capacitor.  The advanced primary-side control used by the LNK419EG device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits.LinkSwitch-PH incorporates a 725 V power FET, a continuous-mode PWM controller, a high-voltage switched current source for self biasing, frequency jittering, protection circuitry including cycle-by-cycle current limit and hysteretic thermal shutdown. 

Features:-

? Single-stage combination of power factor correction and accurate constant-current (CC) output

? Enables very long lifetime designs (no electrolytic capacitors)

? Eliminates optocoupler and all secondary current control circuitry

? Eliminates control loop compensation circuitry

? Simple primary-side PWM dimming interface

? Universal input voltage range
