MP8865 - High-Efficiency 6A 21V Synchronous Step-Down Converter

General Description

The MP8865 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface.

It offers a very compact solution to achieve a 6A continuous output current with excellent load and line regulation over a wide input supply range.

Key Features

  • include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown (TSD). The MP8865 requires a minimal number of readily available, standard, external components and is available in a QFN-15 3mm x 3mm package.

MP8865 High-Efficiency, 6A, 21V, Synchronous Step-Down Converter with I2C Interface DESCRIPTION The MP8865 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. It offers a very compact solution to achieve a 6A continuous output current with excellent load and line regulation over a wide input supply range. The MP8865 has synchronous-mode operation for higher efficiency over the output load range. The reference voltage level can be controlled on-the-fly through the 3.4Mbps I2C serial interface. The voltage range can be adjusted from 0.6V to 1.87V in 10mV steps. Also, the voltage slew rate, switching frequency, enable, and power-saving mode are selectable through the I2C interface.
