MP2307

3A, 23V, 340KHz Synchronous Rectified

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2307 is a monolithic synchronous buck

regulator. The device integrates 100mΩ

MOSFETS that provide 3A of continuous load

current over a wide operating input voltage of

4.75V to 23V. Current mode control provides

fast transient response and cycle-by-cycle

current limit.

•

3A Continuous Output Current,

4A Peak Output Current

Wide 4.75V to 23V Operating Input Range

Integrated 100mΩ Power MOSFET Switches

Output Adjustable from 0.925V to 20V

Up to 95% Efficiency

Programmable Soft-Start

Stable with Low ESR Ceramic Output Capacitors

Fixed 340KHz Frequency

•

An adjustable soft-start prevents inrush current

at turn-on and in shutdown mode, the supply

current drops below 1µA.

Cycle-by-Cycle Over Current Protection

Input Under Voltage Lockout

Thermally Enhanced 8-Pin SOIC Package

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

Networking Systems

FPGA, DSP, ASIC Power Supplies

Green Electronics/Appliances

Notebook Computers
