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 11 for details. NOTE C: White ‘dot’ on top left is pin 1 indicator on top of the device package. Pin Description PIN NAME FUNCTION 1-2, 12, 34-38 NC(SW) 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. 3-4 NC NO CONNECT – These pins may be internally connected. Do not connect to each other or to any other electrical signal. Failure to follow this guideline may result in device damage. 5-11 VOUT Regulated converter output. Connect these pins to the load and place output capacitor between these pins and PGND pins 13-15. 13-18 PGND Input/Output power ground. Connect these pins to the ground electrode of the input and output filter capacitors. See VOUT and PVIN pin descriptions for more details. 19-21 PVIN Input power supply. Connect to input power supply. Decouple with input capacitor to PGND pins 16-18. 22 PG PMOS gate. Connect a 560 Ohm resistor from PVIN to PG. An optional capacitor (22nF) may be placed from PG to BGND to help filter PG in noisy environments. 23 BTMP Bottom plate ground.
