MIC22705 Datasheet High Efficiency Synchronous Buck Regulator

Manufacturer: Microchip Technology

Overview: MIC22705 1 MHz, 7A Integrated Switch, High Efficiency Synchronous Buck.

General Description

The MIC22705 is a highly efficient, 7A, integrated switch, synchronous buck (step-down) regulator.

The MIC22705 is optimized for highest efficiency, achieving more than 95% efficiency while still switching at 1 MHz over a broad range.

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.
