LYT4328E Information

LYTSwitch-4x2x High Power LED Drivers

Power Integrations LYTSwitch-4x2x 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. LYTSwitch-4 ICs are highly integrated and employ a primary-side control technique that eliminates the optoisolator and reduces component count. This allows the use of low-cost single-sided printed circuit boards. Combining PFC and CC functions into a single-stage also helps reduce cost and increase efficiency. The 132 kHz switching frequency permits the use of small, low-cost magnetics. Power Integrations LYTSwitch-4 high power LED drivers do not use primary-side aluminum electrolytic bulk capacitors which greatly extended driver lifetime, especially in bulb and other high temperature applications.
