DESCRIPTION
The MP8848 is a highly integrated and high
frequency synchronous step-down switcher with
I
2
C 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 I
2
C 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 I
2
C interface.
The MP8848 requires a minimum number of
readily available standard external components
and is available in the compact QFN
2mmx3mm package.
