The Future of Analog IC Technology
Primary-Side-Control, Offline LED Controller with Active PFC
DESCRIPTION
The MP4026 is a primary-side-control, offline LED controller that achieves high-power factor and accurate LED current for isolated, singlepower-stage lighting applications in a tiny TSOT23-6 package. It is the next generation of the successful MP4021A. The proprietary realcurrent-control method accurately controls LED current from primary-side information with good line and load regulation. The primary-side-control eliminates the secondary-side feedback ponents and the opto-coupler to significantly simplify LED-lighting-system design.
The MP4026 integrates power-factor...
