General Description

The FAC1484 is a monolithic synchronous buck

regulator. The device integrates two 90m

Ω

MOSFETs, and provides 2A of continuous load current

over a wide input voltage of 4.50V to 23V.Current

mode control providese 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, availablein

an SOP-8E

package,

provides a very compact solution with minimal external

components.
