Product Summary

The LNK417EG is a LinkSwitch-PH LED Driver. The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability (LNK417EG). 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 LinkSwitch-PH device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits. The LNK417EG 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.
