MIC22200
2A Integrated Switch Synchronous Buck Regulator with Frequency
Programmable from 800kHz to 4MHz
General Description
Features
The Micrel MIC22200 is a high-efficiency, 2A integrated switch synchronous buck (step-down) regulator. The MIC22200 switching frequency is programmable from 800kHz to 4MHz, allowing the customer to optimize their designs either for efficiency or for the smallest footprint. The regulator achieves efficiencies as high as 95% while still switching at 1MHz over a broad load range.
The ultra high-speed control loops keep the output voltage within regulation even under the 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.
