DESCRIPTION

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.

An adjustable soft-start prevents inrush current

at turn-on and in shutdown mode, the supply

current drops below 1μA.

This device, available in an 8-pin SOIC

package, provides a very compact system

solution with minimal reliance on external

components.
