MP8869W

High-Efficiency, 12A, 18V, Synchronous Step-Down Converter with I²C Interface

Datasheet

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 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.

Evaluation Tools

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.
