VOUT(Pin1):OutputVoltageFeedback.Aninternalresistive
divider divides the output voltage down for comparison
to the internal 0.6V reference voltage.
VIN (Pin 2): Power Supply Pin. Must be closely decoupled
to GND.
GND (Pin 3): Ground Pin.
SW (Pin 4): Switch Node Connection to Inductor. This pin
connects to the drains of the internal main and synchronous
power MOSFET switches.
VSEL(Pin5):OutputVoltageSelectionPin.Thispincontrols
the regulated output voltage. When tied to GND, VOUT is
1.28V. When oating or connecting this pin to VIN, VOUT
becomes 1.87V.
RUN (Pin 6): Converter Enable Pin. Forcing this pin above
1.5V enables this part, while forcing it below 0.3V causes
the device to shut down. In shutdown, all functions are
disabled drawing <1A supply current. This pin must be
driven; do not oat.
Exposed Pad (Pin 7): GND. The Exposed Pad is ground. It
must be soldered to PCB ground to provide both electrical
contact and optimum thermal performance.
