DESCRIPTION
The MP8869W is a high-frequency, synchronous,
rectified, step-down, switch-mode converter with
I2C control interface. It offers a fully integrated
solution to achieve a 12A continuous and 15A
peak output current with excellent load and line
regulation over a wide input supply range.
In the I2C control loop, the output voltage level
can be controlled on-thefly through an I2C serial
interface. The voltage range can be adjusted from
0.6V to 1.55V in 7.5mV steps. The voltage slew
rate, frequency, current limit, hiccup/latch-off
protection, enable, and power savings mode are
also selectable through the I2C interface.
COT control operation provides fast transient
response. An open drain power good pin indicates
that the output voltage is in the nominal range.
Full protection features include over-voltage
protection, over-current protection, and thermal
shutdown.
The MP8869W is available in a QFN-14(3mmx4mm) package.
