MP2303

3A, 28V, 340KHz Synchronous Rectified

Step-Down Converter

The Future of Analog IC Technology

INITIAL RELEASE – SPECIFICATIONS SUBJECT TO CHANGE

DESCRIPTION

FEATURES

The MP2303 is a monolithic synchronous buck

regulator. The device integrates 120mΩ

MOSFETS that provide 3A continuous load

current over a wide operating input voltage of

4.75V to 28V. Current mode control provides

fast transient response and cycle-by-cycle

current limit.

•

3A Output Current

Wide 4.75V to 28V Operating Input Range

Integrated 120mΩ Power MOSFET Switches

Output Adjustable from 0.8V to 25V

Up to 95% Efficiency

Programmable Soft-Start

Stable with Low ESR Ceramic Output Capacitors

Fixed 340KHz Frequency

Cycle-by-Cycle Over Current Protection

Input Under Voltage Lockout

Thermally Enhanced 8-Pin SOIC Package

An adjustable soft-start prevents inrush current

at turn-on. In shutdown mode, the supply

current drops to 1µA.

This device, available in an 8-pin SOIC

package, provides a very compact system

solution with minimal reliance on external

components.

APPLICATIONS

•

Distributed Power Systems

Pre-Regulator for Linear Regulators

Notebook Computers
