3A, 18V Synchronous Rectified

Step-Down Converter

Description

The AP2953A 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 8-pin SOP package, provides a

very compact system solution with minimal reliance on

external components.
