DESCRIPTION

The

A7230 is a monolithic synchronous buck

regulator. The device integrates 100mΩ MOSFETS

that provide 3A continuous load current over a wide

operating input voltage of 4.75V to 18V. 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

below 1μA.

This device, available in

an SOP 8 package, provides

a very compact system solution with minimal reliance

on external components.

The

A723 0 is available in P SOP8 p ackage
