PIN FUNCTIONS
VFB1 (Pin 1/Pin 1): Regulator 1 Output Feedback. Receives
the feedback voltage from the external resistive divider
across the regulator 1 output. Nominal voltage for this
pin is 0.6V.
RUN1 (Pin 2/Pin 2): Regulator 1 Enable. Forcing this pin
to VIN enables regulator 1, while forcing it to GND causes
regulator 1 to shut down.
MODE (Pin 3/Pin 3): Mode Select Input. To select pulse-
skipping mode, tie to VIN. Grounding this pin selects Burst
Mode operation. Do not leave this pin oating.
SW1 (Pin 4/Pin 4): Regulator 1 Switch Node Connection
to the Inductor. This pin swings from VIN to GND.
VIN (Pin 5/Pin 7): Main Power Supply. Must be closely
de-coupled to GND.
SW2 (Pin 6/Pin 8): Regulator 2 Switch Node Connection
to the Inductor. This pin swings from VIN to GND.
RUN2 (Pin 7/Pin 9): 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/Pin 10): Regulator 2 Output Feedback. Re-
ceives the feedback voltage from the external resistive
divider across the regulator 2 output. Nominal voltage
for this pin is 0.6V.
Exposed Pad (Pin 9/NA): Ground. The Exposed Pad must
be soldered to PCB for optimal thermal performance.
GND (NA/Pins 5, 6): Ground. Connect to the (–) terminal
of COUT, and the (–) terminal of CIN. Pin 5 of the MS pack-
age must be soldered to the PC board for optimal thermal
performance.
