PIN FUNCTIONS
SHDN (Pin 1): Shutdown Pin. This pin is used to enable/
disablethechip.Drivebelow0.3Vtodisablethechip.Drive
above 1.45V to activate the chip. Do not float this pin.
VCC (Pin 2): Input Supply Pin. Must be locally bypassed
to GND. See the Typical Applications section.
GND (Pin 3): Ground. Tie directly to local ground plane.
SW (Pin 4): Switch Pin. This is the collector of the inter-
nal NPN power switch. Minimize the metal trace area
connected to this pin to minimize EMI.
VOUT (Pin 5): Drain of Output Disconnect PMOS. Place
a bypass capacitor from this pin to GND.
CAP (Pin 6): Cathode of the Internal Schottky Diode. Place
a bypass capacitor from this pin to GND.
VREF (Pin 7): Reference Pin. Soft-start can be achieved
by placing a capacitor from this pin to GND. This cap
will be discharged for 70s (typical) at the beginning
of start-up and then be charged to 1.235V with a 10μA
current source.
FBP (Pin 8): Positive Feedback Pin. This pin is the error
amplifier’s positive input terminal. To achieve the desired
output voltage, choose the FBP pin voltage (VFBP) accord-
ing to the following formula:
VFBP =
VOUT
31.85
Forprotectionpurposes,theoutputvoltagecannotexceed
40V even if VFBP is driven higher than VREF.
Exposed Pad (Pin 9): Pin 9 is floating but must be ground-
ed for proper shielding.
