MP8853 2.85V to 18V, 4A, High-Efficiency, Wide-Input, Synchronous, Step-Down Converter with I2C Interface DESCRIPTION The MP8853 is a high-frequency, synchronous, rectified, step-down switch-mode converter with an I2C control interface. The MP8853 offers a fully integrated solution that achieves 4A of continuous output current (IOUT) with excellent load and line regulation across a wide input voltage (VIN) supply range. The output voltage (VOUT) can be controlled on the fly through an I2C serial interface. The reference voltage (VREF) range can be adjusted from 0.6V to 1.108V in 4mV steps. The VOUT slew rate, switching frequency (fSW), current limit, hiccup/latch-off protection, enable, and power-save mode (PSM) can also be selected via the I2C interface.
