MP8861

2.85V - 18V, 6A, High-Efficiency, Wide-Input, Synchronous, Step-Down Converter with Integrated Telemetry via I2C Interface

Datasheet

Description

The MP8861 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. The MP8861 offers a fully integrated solution that achieves 6A of continuous output current with excellent load and line regulation over a wide input 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.

The MP8861 is available in a QFN-14 (3mmx4mm) package.

Highly customizable, the MP8861 is capable of supporting a diverse array of low-voltage applications. Users can program it via MPS I2C GUI; however, changes made in I2C mode will not be retained once the EVB is powered down.

The EVKT8861 is a valuable evaluation tool well-suited for all types of experience levels, from beginner to expert, and can help users quickly determine if the MP8861 is right for their target application.
