The MP8854 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. The MP8854 offers a fully integrated solution that achieves 4A of continuous output current with excellent load and line regulation over a wide input voltage supply range. The output voltage level can be controlled on-the-fly through an I2C serial interface. The reference voltage range can be adjusted from 0.6V to 1.108V in 4mV steps. The voltage slew rate, frequency, current limit, hiccup/latch-off protection, enable and power-save mode (PSM) are also selectable through the I2C interface. Constant-on-time (COT) control operation provides fast transient response. An open-drain power good (PG) pin indicates that the output voltage is in the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP) and thermal shutdown.
