Overview
LYT3314-3328 LYTSwitch-3 Family Single-Stage LED Driver IC with Combined PFC and Constant Current Output for Outstanding TRIAC Dimming in Isolated and Non-Isolated Topologies Product Highlights Combined Single-Stage PFC + Accurate CC Output • Less than ±3% CC regulation over line and load • Power Factor >0.
9 • Ensures monotonic VA reduction with TRIAC phase angle • Low THD, 15% typical for dimmable bulbs, as low as 7% in optimized designs Advanced Integrated TRIAC Dimmer Detection • Detects leading-edge and trailing-edge TRIAC dimmers • High-efficiency mode when no dimmer is present • Selectable dimming profile increases design flexibility • Fast turn-on (<500 ms) • Low pop-on and dead-travel • Active bleeder drive for widest dimmer compatibility Design Flexibility • Supports buck, buck-boost, tapped buck-boost, boost, isolated and non-isolated flyback • Up to 20 W output Highest Reliability • No electrolytic bulk capacitors or optoisolators for increased li...
