PIN DESCRIPTIONS
Pin No.
Name
Description
Application Information
1
VIN
Input supply voltage
Operating input range is 6V to 42V. Transient capability is 45V. A low ESR
capacitor must be placed as close as possible to the VIN and SGND pins.
2
RT
On-time Control
An external resistor from VIN to this pin sets the buck switch on-time, and the
switching frequency.
3
PGD
Power Good
Logic output indicates when the voltage at the FB pin has increased to above
95% of the internal reference voltage. Hysteresis is provided. An external
pull-up resistor to a voltage less than 7V is required.
4
SS
Soft-Start
An internal current source charges an external capacitor to provide the soft-
start function.
5
SGND
Signal Ground
Ground for all internal circuitry other than the current limit sense circuit.
6
FB
Feedback
Internally connected to the regulation comparator. The regulation level is
2.51V.
7
CSG
Current Sense Ground
Ground connection for the current limit sensing circuit. Connect to ground
and to the current sense resistor.
8
CS
Current sense
Connect to the current sense resistor and the anode of the free-wheeling
diode.
9
SW
Switching Node
Internally connected to the buck switch source. Connect to the external
inductor, cathode of the free-wheeling diode, and bootstrap capacitor.
10
BST
Bootstrap capacitor connection of the
Connect a 0.1 µF capacitor from SW to this pin. The capacitor is charged

during the buck switch off-time via an internal diode.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which
operation of the device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.

The human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin.
