The MP8869 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an 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-the-fly through an I2C serial interface. The voltage range can be adjusted from 0.6V to 1.87V in 10mV 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 MP8869 is available in a QFN-14 (3mmx4mm) package.
