MP4027 - MPS

MP4027 Offline LED Controller

The MP4027 is a primary-side-control, offline LED lighting controller. In a tiny TSOT23-8 package, it achieves high power factor (PF) and accurate LED current for isolated, single-powerstage lighting applications. This simplifies LED-lighting-system design significantly by eliminating the secondary-side feedback components and the optocoupler. The MP4027 int.
