VFB1 (Pin 1): Regulator 1 Output Feedback. Receives
the feedback voltage from the external resistor divider
across the regulator 1 output. Nominal voltage for this
pin is 0.6V.
RUN1 (Pin 2): Regulator 1 Enable. Forcing this pin to
VIN enables regulator 1, while forcing it to GND causes
regulator 1 to shut down.
VIN (Pin 3): Main Power Supply. Must be closely decou-
pled to GND.
SW1 (Pin 4): Regulator 1 Switch Node Connection to the
Inductor. This pin swings from VIN to GND.
GND (Pin 5): Ground. Connect to the (–) terminal of COUT,
and the (–) terminal of CIN.
SW2 (Pin 6): Regulator 2 Switch Node Connection to
the Inductor. This pin swings from VIN to GND.
RUN2 (Pin 7): Regulator 2 Enable. Forcing this pin to
VIN enables regulator 2, while forcing it to GND causes
regulator 2 to shut down.
VFB2 (Pin 8): Regulator 2 Output Feedback. Receives
the feedback voltage from the external resistor divider
across the regulator 2 output. Nominal voltage for this
pin is 0.6V.
Exposed Pad (Pin 9): Electrically Connected to GND.
Must be soldered to the PCB for optimum thermal
performance.
