MPS MP4021 Primary Side Control Offline LED Controller

Monolithic Power Systems MP4021 Primary Side Control Offline LED Controller is an off-line LED lighting controller that achieves high power factor and accurate LED current for single-power stage, isolated lighting applications. The proprietary real current control method of the MP4021 Primary Side Offline LED Controller accurately controls the LED current from the primary side, and therefore significantly simplifies the LED lighting system design by eliminating the secondary side feedback components and the optocoupler. The Monolithic Power Systems MP4021 Primary Side Control Offline LED Controller integrates power factor correction and works in boundary conduction mode to reduce the MOSFET switching losses. Applications include solid state, industrial, commercial and residential lighting.
