DESCRIPTION

The

AMS1069 is a monolithic synchronous buck

regulator.

The

device

integrates

two

MOSFETs, and provides 2A of continuous load

current over a wide 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, and in shutdown mode the supply

current drops to 1µA.

This device, available in an

SOP8/ESOP8

package, provides a very compact solution with

minimal external components.
