MP8845C

5A High Efficient Synchronous

Step-Down Switchers with I²C Interface

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP8845C is a highly integrated and high

frequency synchronous step-down switcher with

I²C control interface. It is optimized to support up

to 5A 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 5A Load Current

Internal 32mΩ High-Side, 17mΩ Low-Side

Power MOSFETs

Fixed Frequency Hysteretic Mode Control

I²C Compatible Interface up to 3.4Mbps

I²C Programmable Output Range from 0.6V

to 1.45V in 6.69mV Steps

•

Constant frequency hysteretic control mode

provides extremely fast transient response

without loop compensation and easily achieves

high efficiency under light load condition.

•

Factory Adjustable Switching Frequency from

1MHz to 2.2MHz

I²C Programmable Voltage Transition Slew

Rate

The output voltage level can be controlled, on-the

fly through a 3.4Mbps I²C serial interface.

Voltage range can be adjusted from 0.6V to

1.45V in 6.69mV steps. Voltage slew rate,

switching frequency and power savings mode are

also selectable through the I²C interface.

•

Power Saving Mode Selectable via I2C

Internal Soft-Start

Current Overload and Thermal Shutdown

Protection

Available in 20-ball WLCSP-1.6mmx2mm

package

•

Fully protection features includes internal soft

start, over current protection and over

temperature protection.

APPLICATIONS

•

Processor Core Supply

Micro Converter

The MP8845C requires a minimum number of

readily available standard external components

and is available in the compact WLCSP20-

1.6mmx2mm package.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.
