MIC22400 Datasheet (Microchip) - 4A Integrated Switch Synchronous Buck Regulator

MIC22400, 4A Integrated Switch Synchronous Buck Regulator

MIC22400 is a high-efficiency, 4A integrated switch synchronous buck (step-down) regulator.

MIC22400 is optimized for highest efficiency, achieving over 90% efficiency while still switching at 1 MHz over a broad load range.

The ultra high-speed control loop keeps the output voltage within regulation
