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.
