DESCRIPTION

The MP8869S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. The MP8869S offers a fully integrated solution that achieves 12A of continuous current and 15A of peak output current with excellent load and line regulation over a wide input supply range. The output voltage level can be controlled onthe-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-saving mode 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 when the output voltage is in the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown.

The MP8869S is available in a QFN-14 (3mmx4mm) package.
