GENERAL DESCRIPTION

The MP2307 is a monolithic synchronous buck

regulator.

The

device

integrates

100mΩ

MOSFETS that provide 3A continuous load

current over a wide operating input voltage

range of 4.75V to 23V. Current mode control

provides fast transient response and cycle-by-

cycle current limit.

An adjustable soft-start prevents inrush current

at turn-on. In shutdown mode, the supply

current drops to only 1µA.

This device, available in an 8-pin SOIC

package, provides a very compact system

solution with minimal reliance on external

components.
