MP8847

6A, 6V, High-Efficiency, Synchronous, Step-Down Switcher with I2C Interface

Datasheet

Description

The MP8847 is a highly integrated,high-frequency, synchronous, step-down switcher with an I2C control interface.The MP8847 can support up to 6A of load current over an input supply range from 2.7V to 6V with excellent load and line regulation. Constant-frequency hystereticmode provides an extremely fast transient response without loop compensation to achieve high efficiencyeasilyunderlight-load condition. The output voltage level can be controlled on-the-fly through a 3.4Mbps I2C serial interface. The voltage range can be adjusted from 0.6V to 1.235V in 5mV steps. The voltage slew rate, switching frequency,and power-saving mode are also selectable through the I2C interface. Full protection features include internal soft start, over-current protection (OCP), and over-temperature protection (OTP). The MP8847 requires a minimal number of readily available, standard, external components and is available in a compact QFN-14(2mmx3mm) package.

Evaluation Tools

EVKT-8847 Evaluation Kit 6A, 2.7V-6V, High-Efficiency, Synchronous, Step-Down Converter

Highly customizable, the MP8847 is capable of supporting a diverse array of low-voltage applications. Users can program it via an MPS I2C GUI; however, changes made in I2C mode will not be retained once the EVB is powered down.

The EVKT8847 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 MP8847 is right for their target application.
