The LNK420EG dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability. 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 LNK420EG 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.
Top Features:
- Single-stage power factor correction
- Accurate constant-current output
- Eliminates the need for optocoupler
- Eliminates secondary current control circuitry
