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
