DESCRIPTION

The MP8847 is a highly integrated,high-

frequency, synchronous, step-down switcher

support up to 6A of load current over an input

supply range from 2.7V to 6V with excellent

load and line regulation.

Constant-frequency hysteretic mode provides

an extremely fast transient response without

loop compensation to achieve high efficiency

easily under light-load condition.

The output voltage level can be controlled on-

The voltage range can be adjusted from 0.6V to

1.235V in 5mV steps. The voltage slew rate,

switching frequency, and power-saving mode

Full protection features include internal soft

start, over-current protection (OCP), and over-

temperature protection (OTP).

The MP8847 requires a minimal number of

readily

available,

standard,

external

components and is available in a compact

QFN-14(2mmx3mm) package.
