Ordering Information
Pin Assignments (Top View)
NOTE A: NC pins are not to be electrically connected to each other or to any external signal, ground, or voltage.
However, they must be soldered to the PCB. Failure to follow this guideline may result in part malfunction or damage.
NOTE B: Grey area highlights exposed metal on the bottom of the package that is not to be mechanically or electrically
connected to the PCB. There should be no traces on PCB top layer under these keep out areas.
NOTE C: White ‘dot’ on top left is pin 1 indicator on top of the device package.

FUNCTION
NO CONNECT: These pins are internally connected to the common switching node of the
internal MOSFETs. They must be soldered to PCB but not be electrically connected to any
external signal, ground, or voltage. Failure to follow this guideline may result in device
damage.
Input and output power ground. Connect these pins to the ground electrode of the input and
output filter capacitors. See VOUT, PVIN descriptions and Layout Recommendation for more
details.
Regulated converter output. Connect to the load and place output filter capacitor(s) between
these pins and PGND pins 7 and 8. See layout recommendation for details
