MP28257

4A, Fast Transient, 4.2V-to-20V Input

Synchronous Step-Down Converter

2mmx3mm QFN12

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The

synchronous,

MP28257

fully-integrated,

switch-mode



Wide 4.2V-to-20V Operating Input Range

4A Continuous Output Current

Internal 120mΩ High-Side, 50mΩ Low-

Side Power MOSFETs

Stable with Ceramic Output Capacitors

Proprietary Switching Loss-Reduction

Technology

step-down,

converter with a programmable frequency. It

offers a very compact solution that can provide

up to 4A of continuous output current over a

wide input supply range with excellent load and

line regulation, and can operate at high

efficiency over a wide output current load

range.



Power-Good Indicator

Soft Startup/Shutdown

Constant-on-time control mode provides fast

transient response and eases loop stabilization.

Programmable Switching Frequency

SCP, OCP, OVP, UVP Protection and

Thermal Shutdown

Output Adjustable from 0.815V to 13V

Available in a 2mmx3mm QFN12

Package

Protections include short-circuit protection,

over-current protection, over-voltage protection,

under-voltage protection, and thermal shut

down.



APPLICATIONS

The MP28257 requires a minimal number of

readily-available standard external components.



Networking Systems

Distributed Power Systems

The device is available in a space saving

2mmx3mm QFN12 package that complies with

ROHS.
