PIN FUNCTIONS
ITH/RUN (Pin 1): This pin performs two functions. It serves
as the error amplier compensation point as well as the
run/shutdown control input. Nominal voltage range is 0.7V
to 1.9V. Forcing this pin below the shutdown threshold
(VITHSHDN) causes the LTC3803 to shut down. In shutdown
mode, the NGATE pin is held low.
GND (Pin 2): Ground Pin.
VFB (Pin 3): Receives the feedback voltage from an external
resistive divider across the output.
SENSE (Pin 4): This pin performs two functions. It monitors
switch current by reading the voltage across an external
current sense resistor to ground. It also injects a current
ramp that develops slope compensation voltage across
an optional external programming resistor.
VCC (Pin 5): Supply Pin. Must be closely decoupled to
GND (Pin 2).
NGATE (Pin 6): Gate Drive for the External N-Channel
MOSFET. This pin swings from 0V to VCC.
