MIC22400 4A Integrated Switch Synchronous Buck Regulator with Frequency Programmable up to 4MHz General Description The Micrel MIC22400 is a high efficiency 4A integrated switch synchronous buck (step-down) regulator. The MIC22400 is optimized for highest efficiency and achieves over 90% efficiency while still switching at 1MHz over a broad load range. The ultra high speed control loop keeps www.DataSheet4U.com the output voltage within regulation even under extreme transient load swings commonly found in FPGAs and low voltage ASICs. The output voltage can be adjusted down to 0.7V to address all low voltage power needs. A full range of sequence options are available with the MIC22400.
