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 powersaving mode are selectable through the I2C interface. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include overcurrent 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.
