Title 20 W, Isolated Flyback, TRIAC Dimmable, Power Factor Corrected (>0.98) LED Driver Using LYTSwitchTM-4 LYT4317E
Specification 90 VAC – 132 VAC Input; 36 V, 550 mA Output Application Author Document Number Date Revision PAR38 LED Driver Applications Engineering Department DER-350 May 20, 2013 2.1
Summary and Features High efficiency, ≥85% at 120 VAC Broad dimmer compatibility (within NEMA SSL6 dimming curves) with wide selection of U.S. TRIAC-based dimmers Enhanced user experience Flicker free, monotonic dimming, Fast monotonic start-up (<200 ms) – no perceptible delay Turn on and turn off at almost the same dimming angle – no pop-on Low cost Single-stage combined PFC and accurate primary side regulated constant current output Single-sided PCB; Low component count Integrated protection and reliability features Output open circuit / output short-circuit protected with auto-recovery Fast acting line input overvoltage shutdown extends voltage withstand during line faults Without MOV can withstand ±2500 V ring wave and ±500 V differential surge Auto-recovering thermal shutdown with large hysteresis protects both components and printed circuit board Meets IEC 61000-4-5 ring wave, IEC 61000-3-2 C THD and IEC CISPR 15 / EN55015 B conducted EMI
