Ordering Information

Description

The FR9761

is

a

1.4MHz step-down

DC/DC

converter that provides wide 4.75V to 23V input

voltage range and 2A 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 FR9761 is available in a MSOP-10 package,

which provides a very compact system solution and

good thermal conductance.
