Monolithic Power Systems (MPS) MPQ7200 Buck Synchronous LED Driver

Monolithic Power Systems (MPS) MPQ7200 Buck Synchronous LED Driver is a high-frequency, constant-current, driver with integrated power MOSFETs. The MPQ7200 is a compact solution to achieve up to 1.2A of continuous output current. The device has excellent load and line regulation across a wide input supply range. The MPQ7200 can also be configured for buck mode to provide up to 3A of constant load current.
