Datasheet (EN)

Product Description

The MP8868 is a high-frequency, synchronous, rectified, stepdown, switch-mode converter with an I2C control interface. Its fully integrated solution achieves a 10A output current with excellent load and line regulation over a wide input-supply range.

The reference voltage level is controlled on-the-fly by the I2C serial interface with the reference voltage range adjustable from 0.6V to 1.87V in 10mV steps. In addition, the voltage scaling slew rate, the switching frequency, enable, and power-save mode are selectable through the I2C interface.

Current-mode operation provides fast transient response and eases loop stabilization. EN/SYNC supports external clock synchronization, and an open-drain power good pin indicates when the output voltage is in the nominal range. Full protection features include:

• Over-voltage protection (OVP)
• Hiccup over-current protection (OCP)
• Thermal shutdown

The MP8868 requires a minimal number of readily available, standard, external components, and it is available in a QFN-14 (3x4mm) package.
