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: Shaded area highlights exposed metal below the package that is not to be mechanically or electrically
connected to the PCB. Refer to Figure 10 for details.
NOTE C: White ‘dot’ on top left is pin 1 indicator on top of the device package.

FUNCTION
NO CONNECT – These pins may be internally connected. Do not connect them to each
NC NC other or to any other electrical signal. Failure to follow this guideline may result in device
damage.
VOUT
O
Regulated converter output. Connect these pins to the load and place output capacitor
between these pins and PGND pins 29-34.
NO CONNECT – These pins are internally connected to the common switching node of the
NC(SW) NC internal MOSFETs. They are not to be electrically connected to any external signal, ground,
or voltage. Failure to follow this guideline may result in damage to the device.
