Pin Description
PIN NUMBER

NAME
SW
DESCRIPTION
APPLICATION INFORMATION
Internally connected to the buck switch source.
Connect to the inductor, free-wheeling diode, and
bootstrap capacitor.
Connect a 0.022 μF capacitor from SW to this pin.
The capacitor is charged from V
CC
via an internal
diode during each off-time.
The re-circulating current flows through the internal
sense resistor, and out of this pin to the
free-wheeling diode. Current limit is nominally set at
1.25A.
Re-circulating current flows into this pin to the
current sense resistor.
Ground for all internal circuitry other than the current
limit detection.
Internally connected to the regulation and
over-voltage comparators. The regulation level is
2.5V.
An internal 11.5 μA current source charges an
external capacitor to 2.5V, providing the softstart
function.
An external resistor from V
IN
to this pin sets the
buck switch on-time. Grounding this pin shuts down
the regulator.
Nominally regulates at 7.0V. An external voltage
(7.5V-14V) can be applied to this pin to reduce
internal dissipation. An internal diode connects V
CC
to V
IN
.
Nominal input range is 8.0V to 75V.
No internal connection.
