Description
Power Integrations LNK419EG LED Lighting Driver 90VAC to 265VAC 0.5A SIP-7C Through Hole RoHS
The LNK419EG is a LinkSwitch™-PH dramatically simplifies implementation LED Driver requiring long lifetime and high efficiency. 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. LinkSwitch™-PH incorporates a 725V 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.
