ISN (Pin 2):
Current Sense (–) Pin. The inverting input to
the current sense amplifier.
ISP (Pin 3):
Current Sense (+) Pin. The noninverting input
to the current sense amplifier.
I
ADJ
(Pin 4):
Current Sense Adjust Pin. A DC voltage
applied to this pin will reduce the current sense voltage. If
this adjustment is not needed, tie this pin to ground.
GND (Pin 5):
Ground Pin. Tie this pin directly to local
ground plane.
SW (Pin 7 ):
Switch Pin. This is the collector of the internal
NPN power switch. Minimize the metal trace area con-
nected to this pin to minimize EMI.
V
IN
(Pin 8):
Input Supply Pin. Bypass this pin with a
capacitor to ground as close to the device as possible.
SHDN (Pin 9):
Shutdown Pin. Tie this pin higher than 1V
to turn on the LT1618; tie below 0.3V to turn it off.
V
C
(Pin 10):
Compensation Pin for Error Amplifier. Con-
nect a series RC from this pin to ground. Typical values are
2k
and 10nF.
