LNK415EG [Power Integrations]

The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability. It features a single-stage combined power factor and constant-current controller that eliminates a switching stage and the electrolytic bulk capacitor. The advanced primary-side control provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits. Key features include: single-stage PFC, long lifetime designs (no electrolytic capacitors), elimination of optocoupler and secondary current control, simple primary-side PWM dimming interface, universal input voltage range, and flicker-free TRIAC dimming. EcoSmart energy efficiency: >90% achievable, reduced component count, no current sense resistors, low standby power. Advanced protection: auto-restart for short-circuit, open circuit fault detection, thermal shutdown. Green package: halogen free and RoHS compliant.
