Microchip | MIC22200YML-TR

The MIC22200YML TR is a high efficiency, 2 A integrated switch synchronous buck (step-down) regulator. The MIC22200 switching frequency is programmable from 800 kHz to 4 MHz, 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.
