MIC22400 Description
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 even under extreme transient load swings monly found in FPGAs and low-voltage ASICs.
