MP2303A

3A, 28V, 360kHz Synchronous Rectified

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2303A is a monolithic synchronous

buck regulator. The device integrates a 150mΩ

high-side MOSFET and a 80mΩ low-side

MOSFET that provide 3A continuous load

current over a wide operating input voltage of

4.7V to 28V. Current mode control provides fast

transient response and cycle-by-cycle current

limit.



3A Output Current

Wide 4.7V to 28V Operating Input Range

Integrated MOSFET Switches

Output Adjustable from 0.80V to 25V

Up to 95% Efficiency

Programmable Soft-Start

Stable with Low ESR Ceramic Output Capacitors

Fixed 360kHz Frequency

Cycle-by-Cycle Over Current Protection

Input Under Voltage Lockout

Available in thermally enhanced 8-Pin SOIC

and PDIP-8 packages

An adjustable soft-start prevents inrush current

at turn-on. In shutdown mode, the supply

current drops to lower than 1μA.

This device, available in an 8-pin SOIC and

PDIP-8 packages, provides a very compact

system solution with minimal reliance on

external components.

APPLICATIONS



Distributed Power Systems

Pre-Regulator for Linear Regulators

Notebook Computers
