Microchip Technology MIC22200
The MIC22200 is a high-efficiency, 2A 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 1 MHz over a broad load range.| Part No. | MIC22200 |
