Описание
LYTSwitch™-4 is a single-stage accurate primary-side constant current (CC) controller with PFC for high-line applications with TRIAC dimming and non-dimming options. 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 132KHz switching frequency permits the use of small, low cost magnetics. LED drivers using the LYTSwitch-4 family do not use primary side aluminium electrolytic bulk capacitors. This means greatly extended driver lifetime, especially in bulb and other high temperature applications. LYTSwitch-4 family provides excellent turn-on characteristics for leading-edge and trailing-edge TRIAC dimming applications.
