ITH/RUN (Pin 1): This pin performs two functions. It
serves as the error amplifier compensation point as well as
the run/shutdown control input. Nominal voltage range is
0.7V to 1.9V. Forcing this pin below 0.28V causes the
LTC3803-3 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 exter-
nal resistive divider across the output.
SENSE (Pin 4): This pin performs two functions. It moni-
tors 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.
