PIN FUNCTIONS
VIN (Pin 1): The VIN pin supplies current to the LT3653’s
internal regulator and the internal power switch. Locally
bypass this pin with a capacitor.
HVOK (Pin 2): The HVOK pin is a status pin which indi-
cates that the internal bias rail is present and that an input
undervoltage lockout fault, an overvoltage lockout fault or
an over temperature fault are not present.
VC (Pin 3): The VC pin is the output of the internal error
amplier and is internally compensated. The voltage on this
pin controls the peak switch current. Connect this pin to
the battery charger VC pin for battery tracking function.
ILIM (Pin 4): Connect a resistor to GND to program the
output current limit of the regulator. See the ILIM Resistor
section in Application Information.
VOUT (Pin 5): The VOUT pin is connected to the negative
terminal of the internal current sense resistor of the output
current limit circuit. Maximum VOUT voltage is regulated
to 4.8V.
ISENSE (Pin 6): The ISENSE pin is the positive input to the
internal current sense resistor of the output current limit
circuit. The ISENSE pin is also the anode of the internal
BOOST diode.
BOOST (Pin 7): The BOOST pin provides a drive voltage,
higher than the input voltage, to the internal power switch.
The BOOST pin is internally connected to the cathode of
the BOOST diode.
SW (Pin 8): The SW pin is the output of the internal power
switch. Connect this pin to the inductor, catch diode and
boost capacitor.
Exposed Pad (Pin 9): Ground. The Exposed Pad must be
soldered to the PCB and electrically connected to ground.
Use a large ground plane and vias to optimize thermal
performance.
