Information:
NO CONNECT – These pins may be internally connected. Do not connect them to each
other or to any other electrical signal. Failure to follow this guideline may result in device
damage.
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
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.
