MP4059GS Description
The MP4059 is a single-stage PFC flyback controller for LED deep-dimming applications. The MP4059 can regulate constant current to an LED load over a wide 1% to 100% dimming range without flickering or shimmering. The MP4059 is a primary-side controller without any secondary-side feedback ponents or optocouplers, simplifying the LED driver design significantly.
