PIN FUNCTIONS
FB (Pin 1/Pin 3): Feedback. Place resistor to negative
output here. Set resistor value R1 = VOUT/10A.
GND (Pins 2, 3/Pin 2): Ground. For DFN package, tie both
pin 2 and pin 3 together to ground.
SW (Pin 4/Pin 1): Switch. Connect to external inductor
L1 and positive terminal of transfer capacitor.
VIN (Pin 5/Pin 6): Input Supply. Must be locally bypassed
with 1F or greater.
NC (Pin 6/NA): No Internal Connection.
D (Pin 7/Pin 5): Anode Terminal of Integrated Schottky
Diode. Connect to negative terminal of transfer capaci-
tor and external inductor L2 (flyback configuration) or
to cathode of external Schottky diode (inverting charge
pump configuration).
SHDN (Pin 8/Pin 4): Shutdown. Connect to GND to turn
device off. Connect to supply to turn device on.
Exposed Pad (Pin 9/NA): GND. The exposed pad should
be soldered to the PCB ground to achieve the rated thermal
performance.
