Pin Description
PIN
NAME
DESCRIPTION
APPLICATION INFORMATION
1
SW
Switching Node
Internally connected to the buck switch source.
Connect to the external inductor, diode, and boost
capacitor.
2
BST
Boost pin for boot-strap capacitor
Connect a 0.022 µF capacitor from SW to this pin. An
internal diode charges the capacitor during the
off-time.
3I
SEN
Current sense input
Internally the current sense resistor connects from this
pin to S
GND. Re-circulating current flows out of this pin
to the free-wheeling diode. Current limit is set at
1.25A.
4S
GND
Sense Ground
Re-circulating current flows into this pin to the current
sense resistor.
5
RTN
Circuit Ground
Ground for all internal circuitry other than the current
limit detection.
6
FB
Feedback
Internally connected to the regulation and over-voltage
comparators. The regulation level is 2.5V.
7
SS
Softstart
An internal 11.5 µA current source charges an external
capacitor to 2.5V to provide the softstart function.
8R
ON/SD
On-time Control and Shutdown
An external resistor from V
IN to this pin sets the buck
switch on-time. Grounding this pin shuts down the
regulator.
9V
CC
Output from the start-up regulator
Nominally regulated to 7.0V. An external voltage
(8V-14V) can be connected to this pin to reduce
internal dissipation. An internal diode connects V
CC to
V
IN.
10
V
IN
Input supply voltage
Nominal input range is 8.0V to 36V.
