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 the fly 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.

EVKT-8869W Evaluation Kit 3V-18V, 12A, High-Efficiency, Wide-Input, Synchronous, Step-Down Converter
The MP8869W is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. The MP8869W offers a fully integrated solution that achieves 12A of continuous and 15A of peak output current with excellent load and line regulation over a wide input supply range.
Highly customizable, the MP8869W is capable of supporting a diverse array of applications. Users can program it via MPS I2C GUI; however, changes made in I2C mode will not be retained once the EVB is powered down.
The EVKT8869W is a valuable evaluation tool well-suited for all types of experience levels, from beginner to expert, and can help users quickly determine if the MP8869W is right for their target application.
Configure multiple parameters of the MP88xx including output voltage and fsw.
