                      Product Overview

                      LYTSwitch™-3 family is ideal for single-stage power factor corrected constant current LED bulbs and downlighters. Each device incorporates a high-voltage power MOSFET and discontinuous mode, variable frequency variable on-time controller. The controller also provides cycle-by-cycle current limit, output OVP, line overvoltage, comprehensive protection features, plus advanced thermal management circuitry. All LYTSwitch-3 ICs have a built-in TRIAC detector that discriminates between leading-edge and trailing-edge dimmers. This capability together with load monitoring circuitry regulates bleeder current during each switching cycle. The controller disables the bleeder circuit completely if no dimmer is detected, significantly increasing efficiency. The combination of a low-side switching topology, cooling via electronically quiet SOURCE pins and frequency jitter ensure extremely low EMI. This reduces size of input filter components, greatly reducing audible noise during dimming.

                      • Output power of 5.7W at 85-132VAC or 185-265VAC
                      • Combined single stage PFC + accurate CC output, advanced integrated TRIAC dimmer detection
                      • Design flexibility and highest reliability
                      • Less than ±3% CC regulation over line and load, power factor <gt/>0.9
                      • Ensures monotonic VA reduction with TRIAC phase angle
                      • Supports buck, buck-boost, tapped buck-boost, boost, isolated and non-isolated flyback
                      • No electrolytic bulk capacitors or optoisolators for increased lifetime
                      • Input and output overvoltage, output short-circuit/open-loop protection, advanced thermal control
                      • Selectable dimming profile increases design flexibility, fast turn-on (<lt/>500ms)
                      • Low THD, 15% typical for dimmable bulbs, as low as 7% in optimized designs
