Note 2:
The LT3483E is guaranteed to meet specifications from 0°C to 85°C.
Specifications over the –40°C to 85°C operating temperature range are
assured by design, characterization and correlation with statistical process
controls. The LT3483I is guaranteed to meet specifications over the –40°C to
125°C operating temperature range.
Note 3:
Current flows out of the pin.

PIN FUNCTIONS
(DFN/TSOT-23)
FB (Pin 1/Pin 3):
Feedback. Place resistor to negative
output here. Set resistor value R1 = V
OUT
/10μA.
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.
V
IN
(Pin 5/Pin 6):
Input Supply. Must be locally bypassed
with 1μF or greater.
NC (Pin 6/NA):
No 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
