Microchip Technology MIC22601
The MIC22601 is a high efficiency 6A Integrated switch synchronous buck (step-down) regulator. The MIC22601 is optimized for highest efficiency (greater than 90%), while still switching at 4 MHz over a broad load range with only 0.22 μH inductor and down to 22 μF output capacitor. The ultra-high speed control loop keeps the output voltage within regulation even under extreme transient load swings commonly found in FPGAs and low voltage ASICs.| Part No. | MIC22601 |

GENERAL DESCRIPTION
The output voltage can be adjusted down to 0.7V to address all low voltage power needs. A full range of sequencing and tracking options is available with the MIC22601. The EN/DLY pin combined with the Power Good PG/POR pin allows multiple outputs to be sequenced in any way during turn-on and turn-off.
