The MP4021 is a primary-side–control offline LED lighting controller that achieves high power factor and accurate LED current for isolated single-power-stage lighting applications in a single SOIC8 package. The proprietary realcurrent control method accurately controls LED current from primary-side information. Eliminating the secondary-side feedback components and the optocoupler significantly simplifies the LED lighting system design.
