The LYTSwitch-4 family of devices are highly integrated monolithic switching ICs optimized to provide an isolated, dimmable (NEMA complaint), high power factor (PF), constant current driver for LED lighting applications at output powers of up to 78 W applications. LYTSwitch-4 devices reduce circuit complexity by integrating the power MOSFET and controller plus eliminating the optocoupler and all secondary side feedback components
