SW (Pin 1): Switch Node Connector to Inductor. This pin
connects to the drains of the internal main and synchronous
power MOSFET switches.
CAP (Pin 2): Capacitor used for smoothing out spread
spectrum or for PLL response. Connect to a capacitor
whose other plate is connected to GND, or allow the pin
to oat. Value = 1nF – 10nF.
MODE (Pin 3): Mode Selection Pin. Connect as follows
to invoke desired operation: MODE = GND
→ Burst Mode
operation, MODE = VFB
→ Pulse skip with spread spec-
trum, MODE = VIN
→ Pulse skip, MODE = External clock
→ PLL mode.
VFB (Pin 4): Feedback sensing pin for the external feedback
resistors.
RUN (Pin 5): Run Control Input. Forcing pin above 1.5V
enables the part. Forcing the pin below 0.3V shuts down
the device. In shutdown, all functions are disabled,
drawing <1μA of supply current. Do not leave the RUN
pin oating.
VIN (Pin 6): Main Supply Pin.
Exposed Pad (Pin 7): Exposed Pad connected to
ground.
