MP4657B LED Driver & System Voltage Controllers

Monolithic Power Systems (MPS) MP4657B 4-String LED Driver and System Voltage Controllers are built for LED backlighting on the secondary side. The MP4657B controls the flyback power stage and utilizes an external N-channel MOSFET to regulate the system output voltage, and the LED current loop with integrated 4-string LED current balancing. Implementing a 4V to 16V input voltage, the device outputs a direct driving signal to control the N-channel MOSFET for regulating the system output voltage. Furthermore, the device outputs a compensation signal to control the primary-side flyback (or other power stages) through an optocoupler.
