6A High Efficient Synchronous Step-Down Converter with I2C Interface
The EV8865-Q-00A is used for demonstrating the performance of MPS’s MP8865. MP8865 is a highly integrated and high frequency synchronous step-down switcher with I2C control interface. It is optimized to support up to 6A load current over an input supply range from 4.5V to 21V with excellent load and line regulation.
Current-Mode operation provides fast transient response and eases loop stabilization. The output voltage level can be controlled, on-the fly through a 3.4Mbps I2C serial interface. Voltage range can be adjusted from 0.6V to 1.87V in 10mV steps. Voltage slew rate, switching frequency and power savings mode are also selectable through the I2C interface. Fully protection features includes over current protection, over voltage protection and over temperature protection.
MP8865 is available in QFN15 (3mmx3mm) package.

21V, 6A, High-Efficiency, Sync, Step-Down Converter with I2C Interface
The MP8865 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. The MP8865 offers a very compact solution that achieves 6A of continuous output current with excellent load and line regulation over a wide input supply range. The MP8865 uses synchronous-mode operation for higher efficiency over the output load range.
Highly customizable, the MP8865 is capable of supporting a diverse array of mid-voltage applications. Users can program it via an MPS I2C GUI; however, changes made in I2C mode will not be retained once the EVB is powered down.
The EVKT8865 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 MP8865 is right for their target application.
