Ordering Information

Description

The

FR9765

is

a

1.4MHZ step-down DC/DC

converter that provides wide 4.75V to 24V input

voltage range and 3A continuous load current

capability.

Fault protection includes cycle-by-cycle current limit,

input UVLO and thermal shutdown.

Besides,

adjustable soft-start function prevents inrush current

at turn-on.

This device uses current mode control

scheme that provides fast transient response.

In

shutdown mode, the supply current is about 10

μA.

The FR9765 is available in SOP-8 (exposed pad)

package, which provides a very compact system

solution and good thermal conductance.
