DESCRIPTION

The MP8847 is a highly integrated and high

frequency synchronous step-down switcher with

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-

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

The MP8847 requires a minimum number of

readily available standard external components

and

is

available

in

the

compact

QFN

2mmx3mm package.
