MP8848

6A, High-Efficiency, Synchronous,

Step-Down Switcher with I²C Interface

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP8848 is a highly integrated, high-

frequency, synchronous, step-down switcher

with an I²C control interface. The MP8848 can

support up to 6A of load current over an input

supply range from 2.7V to 6V with excellent

load and line regulation.



2.7V to 6V Input Voltage Range

Up to 6A Load Current

Internal 32mΩ High-Side and 15mΩ Low-

Side Power MOSFETs



I²C-Compatible Interface up to 3.4Mbps

I²C-Programmable Output Range from 0.6V

to 1.235V in 5mV Steps

Constant-frequency hysteretic mode provides

an extremely fast transient response without

loop compensation to achieve high efficiency

easily under light-load condition.



Factory Adjustable Switching Frequency

from 0.85MHz to 2.2MHz



Power-Saving Mode Selectable via I²C

Internal 1ms Soft Start

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.
