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

Product Detail

The MP8865 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with a 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 a 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. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP), over-voltage protection (OVP), and thermal shut down (TSD). The MP8865 requires a minimal number of readily available, standard, external components and is available in a 15-pin QFN15 (3x3mm) package.
