The MP8869GL-Z is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. It offers a fully integrated solution that achieves 12A of continuous and 15A of peak output current with excellent load and line regulation over a wide input supply range.In the I2C control loop, the output voltage level can be controlled on-the-fly through an I2C serial interface. The voltage range can be adjusted from 0.6V to 1.87V in 10mV steps. 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 that the output voltage is in the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown.The MP8869GL-Z is available in a QFN-14 (3mmx4mm) package. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
