DESCRIPTION

The MP8868 is a high-frequency, synchronous,

rectified, stepdown, switch-mode converter with

an I2C control interface. Its fully integrated

solution achieves a 10A output current with

excellent load and line regulation over a wide

input-supply range.

The reference voltage level is controlled on-the-

voltage range adjustable from 0.6V to 1.87V in

10mV steps. In addition, the voltage scaling

slew rate, the switching frequency, enable, and

power-save mode are selectable through the

I2C interface.

Current-mode operation provides fast transient

response

and

eases

loop

stabilization.

EN/SYNC

supports

external

clock

synchronization, and an open-drain power good

pin indicates when the output voltage is in the

nominal range. Full protection features include:

• Over-voltage protection (OVP)

• Hiccup over-current protection (OCP)

• Thermal shutdown

The MP8868 requires a minimal number of

readily

available,

standard,

external

components, and it is available in a QFN-14

(3x4mm) package.

FEATURES

• Wide 4.5V-to-17V Operating Input Range

• 1% Internal Reference Accuracy
