EV2307DN-00A

3A, 23V, 340KHz

Synchronous Step-Down Converter

EVALUATION BOARD 鈥?INITIAL RELEASE

The Future of Analog IC Technology

GENERAL DESCRIPTION

The MP2307 is a monolithic synchronous buck

regulator. The device integrates 100m鈩?/div>

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 1碌A(chǔ).

This device, available in an 8-pin SOIC

package, provides a very compact system

solution with minimal reliance on external

components.
