LTC1626
PWR V
IN
(Pins 1, 13):
Supply for the Power MOSFET and
Its Driver. Decouple this pin properly to ground.
V
IN
(Pin 2):
Main Supply for All the Control Circuitry in
the LTC1626.
LBO
(Pin 3):
Open-Drain Output of the Low-Battery Com-
parator. This pin will sink current when Pin 4 (LBI) goes
below 1.25V. During shutdown, this pin is high imped-
ance.
LBI
(Pin 4):
The (–) Input of the Low-Battery Comparator.
The (+) input is connected to a reference voltage of 1.25V.
If not used, connect to V
IN
.
C
T
(Pin 5):
External capacitor C
T
from Pin 5 to ground sets
the switch off-time. The operating frequency is dependent
on the input voltage and C
T
.
I
TH
(Pin 6):
Feedback Amplifier Decoupling Point. The
current comparator threshold is proportional to Pin 6
voltage.
PI
FU
CTIO
N
S
U
U
SENSE
(Pin 7):
Connects to the (–) Input of the Current
Comparator.
SENSE
+
(Pin 8):
The (+) Input to the Current Comparator.
A built-in offset between Pins 7 and 8 in conjunction with
R
SENSE
sets the current trip threshold.
V
FB
(Pin 9):
This pin serves as the feedback pin from an
external resistive divider used to set the output voltage.
SHDN (Pin 10):
Shutdown Pin. Pulling this pin to V
IN
keeps the internal switch off and puts the LTC1626 in
micropower shutdown. If not used, connect to SGND.
SGND (Pin 11):
Small-Signal Ground. Must be routed
separately from other grounds to the (–) terminal of C
OUT
.
PWR GND (Pin 12):
Switch Driver Ground. Connects to
the (–) terminal of C
IN
.
SW (Pin 14):
Drain of the P-Channel MOSFET Switch.
Cathode of the Schottky diode must be connected closely
to this pin.
