LNK419EG – 500mA Power Integrations-LED Driver Off-Line Switcher IC – eSIP-7C Package
The LinkSwitch™-PH dramatically simplifies the 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 eliminate a switching stage and the electrolytic bulk capacitor. The advanced primary-side control used by the LinkSwitch-PH 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.
