The MP8847 is a highly integrated and high frequency synchronous step-down switcher with I²C control interface. It is optimized to support up to 6A load current over an input supply range from 2.7V to 6V with excellent load and line regulation.

Constant frequency hysteretic mode provides extremely fast transient response without loop compensation and easily achieves high efficiency under light load condition.

The output voltage level can be controlled, on-the fly through a 3.4Mbps I²C serial interface.  Voltage range can be adjusted from 0.6V to 1.235V in 5mV steps. 

Voltage slew rate, switching frequency and power savings mode are also selectable through the I²C interface.

The MP8847 requires a minimum number of readily available standard external components and is available in the compact QFN 2mmx3mm package.
