Power Integrations LYTSwitch-4 high power LED drivers feature a wide dimming range and fast start-up, even when turning-on from a low conduction angle and easily meet international requirements for THD and harmonics. Output current is tightly regulated with better than ±5% CC tolerance1. Efficiency of up to 92% is achieved in typical applications. LYTSwitch-4 drivers provide excellent turn-on characteristics for leading-edge and trailing-edge TRIAC dimming applications.
