PIN FUNCTIONS
VC (Pin 1): The VC pin is the output of the internal error
amplier. The voltage on this pin controls the peak switch
current. Tie an RC network from this pin to ground to
compensate the control loop.
FB (Pin 2): The LT3682 regulates the FB pin to 0.8V. Connect
the feedback resistor divider tap to this pin.
PG (Pin 3): The PG pin is the open collector output of an
internal comparator. PG remains low until the FB pin is
within 10% of the nal regulation voltage. PG output is
valid when VIN is above the minimum input voltage and
RUN/SS is high.
GND (Pin 4): The GND pin is the ground of all the internal
circuitry. Tie directly to the local GND plane.
BD (Pin 5): This pin connects to the anode of the boost
Schottky diode. BD also supplies current to the LT3682’s
internal regulator.
BOOST (Pin 6): This pin is used to provide a drive volt-
age, higher than the input voltage, to the internal bipolar
NPN power switch. Connect a capacitor (typically 0.22μF)
between BOOST and SW.
DA (Pin 7): Connect the anode of the catch diode (D1
in Block Diagram) to this pin. Internal circuitry senses
the current through the catch diode providing frequency
foldback in extreme situations.
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.
RUN/SS (Pin 9): The RUN/SS pin is used to put the LT3682
in shutdown mode. Tie to ground to shut down the LT3682.
Tie to 2.5V or more for normal operation. RUN/SS also
provides a soft-start function; see the Applications Infor-
mation section for more information.
RT (Pin 10): Oscillator Resistor Input. Connect a resistor
from this pin to ground to set the switching frequency.
SYNC (Pin 11): This is the external clock synchronization
input. Ground this pin for low ripple Burst Mode operation
at low output loads. Tie to 0.8V or more for pulse skipping
mode operation. Tie to a clock source for synchronization.
Clock edges should have rise and fall times faster than
1μs. Note that the maximum load current depends on
which mode is chosen. See the Applications Information
section for more information.
VIN (Pin 12): The VIN pin supplies current to the LT3682’s
internal regulator and to the internal power switch. This
pin must be locally bypassed.
ExposedPad(Pin13):PGND.Thisisthepowergroundused
by the catch diode (D1) when its anode is connected to the
DA pin. The exposed pad must be soldered to the PCB.
