MP28248

High-Efficiency, Fast-Transient, 3A, 4.2V-20V Input

Synchronous Step-down Converter

in a QFN12 (2x3mm) Package

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP28248 is a fully-integrated, high-

efficiency, synchronous, step-down, switch

mode converter. It offers a very compact

solution that can achieve a 3A continuous

output current over a wide input supply range

with excellent load and line regulation. The

MP28248 operates at high efficiency over a

wide output-current load range.



Wide 4.2V to 20V Operating Input Range

3A Output Current

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching-Loss Reduction

Technique



Soft Startup/Shutdown

Programmable Switching Frequency

SCP, OCP, UVP, OVP, and Thermal

Shutdown

Output Adjustable from 0.815V to 13V

Available in a QFN12 (2mmx3mm) Package

Constant-On-Time control mode provides fast

transient response and eases loop stabilization.



Full protective features include short-circuit

protection, over-current protection, over-voltage

protection, under-voltage protection, and

thermal shutdown.

APPLICATIONS



Networking Systems

Distributed Power Systems

The MP28248 requires a minimal number of

readily-available standard external components.

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

green status, please visit MPS website under the Products, Quality

Assurance page.

This device is available in a space-saving

2mmx3mm 12-pin QFN package.
