MP8847
The Future of Analog IC Technology
6A, 2.7V-6V, High-Efficiency, Synchronous,
Step-Down Switcher with I2C Interface
In 2x3mm QFN
DESCRIPTION
FEATURES
The MP8847 is a highly integrated, highfrequency, synchronous, step-down switcher
with an I2C control interface. The MP8847 can
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 onthe-fly through a 3.4Mbps I2C serial interface.
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
are also selectable through the I2C interface.
Full protection features include internal soft
start, over-current protection (OCP), and overtemperature protection (OTP).
The MP8847 requires a minimal number of
readily
available,
standard,
external
components and is available in a compact
QFN-14(2mmx3mm) package.
