MP4030A Datasheet | Monolithic Power Systems

The Future of Analog IC Technology TRIAC-Dimmable, Primary-Side-Control Offline LED Controller with Active PFC DESCRIPTION The MP4030A is a TRIAC-dimmable, primaryside-control, offline LED lighting controller with active PFC. It can output an accurate LED current for an isolated lighting application with a single-stage converter. The proprietary realcurrent-control method can accurately control the LED current using primary-side information. It can significantly simplify LED lighting system design by eliminating secondary-side feedback ponents and the optocoupler. The MP4030A implements power-factor correction and works in boundary-conduction mode to reduce MOSFET switching...
