DESCRIPTION

The MP8861 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with an I2C control interface. The MP8861 offers

a fully integrated solution that achieves 6A of

continuous output current with excellent load

and line regulation over a wide input supply

range.

The output voltage level can be controlled onthe-

fly through an I2C serial interface. The

reference voltage range can be adjusted from

0.6V to 1.108V in 4mV steps. The voltage slew

rate, frequency, current limit, hiccup/latch-off

protection, enable, and power-save mode (PSM)

are also selectable through the I2C interface.

Constant-on-time (COT) control operation

provides fast transient response. An open-drain

power good (PG) pin indicates that the output

voltage is in the nominal range. Full protection

features include over-voltage protection (OVP),

over-current protection (OCP), and thermal

shutdown.

The MP8861 is available in a QFN-14

3mmx4mm) package.
