CTRL (Pin 1):
Internal Reference Override Pin. This allows
the FB voltage to be externally set between 0V and 1.25V.
Tie this pin to above 1.5V (V
IN
for example) to use the
internal 1.25V reference.

FB (Pin 2):
Feedback Pin. The LT3464 regulates its feed-
back pin to 1.25V if the internal reference is used or to
V

if the CTRL pin is between 0V and 1.25V. Connect
the feedback resistor divider tap to this pin. Set the output
voltage by selecting R1 and R2.

OUT (Pin 3):
PNP Collector. This is the output of the
Output Disconnect circuit. Bypass this pin with at least a
0.1
μ
F capacitor connected to the CAP pin or to ground.
GND (Pin 4):
Ground. Tie this pin directly to the ground
plane.
CAP (Pin 5):
PNP Emitter and Schottky Cathode. This pin
connects to the output capacitor, and optionally to the
phase-lead capacitor.
SW (Pin 6):
Switch Pin and Schottky Anode. This is the
collector of the internal NPN power switch. Minimize the
metal trace area connected to the pin to minimize EMI.

IN
(Pin 7):
Input Supply Pin: Bypass this pin with a
capacitor located as close to the device as possible.
SHDN (Pin 8):
Shutdown Pin. This pin is used to put the
device in shutdown mode. Tie the pin low to shut down the
LT3464. Tie high for normal operation See the electrical
specifications for the required voltages.
