DESCRIPTION
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.
