Description

MPL

Optimized Performance with MPS Inductor

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 up to 4A of continuous output current (I_OUT), with excellent load and line regulation across a wide input voltage (V_IN) supply range.

The output voltage (V_OUT) can be controlled on the fly through an I²C serial interface. The reference voltage (V_REF) range can be adjusted from 0.6V to 1.108V in 4mV steps. The V_OUT slew rate, switching frequency (f_SW), current limit, hiccup/latch-off protection, enable (EN), and power-save mode (PSM) can also be selected via the I²C interface.

Constant-on-time (COT) control provides fast transient response. An open-drain power good (PG) pin indicates whether V_OUT is within the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown.

The MP8853 is available in a QFN-14 (3mmx3mm) package.
