4. Connect the power supply.
First, prepare the AC adapter for the country where it will be used by selecting the plug.
The LP3500 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and
European style plugs. Snap in the top of the plug assembly into the slot at the top of the
AC adapter as shown in Figure 4, then press down on the spring-loaded clip below the
plug assembly to allow the plug assembly to click into place.
Hook up the connector from the wall transformer to header J5 on the Prototyping Board as
shown in Figure 4. The orientation of this connector is not important since the VIN (posi-
tive) voltage is the middle pin, and GND is available on both ends of the three-pin header
J5.
5. Apply power.
Plug in the AC adapter. If you are using your own power supply, it must provide 3 V to
30 V DC—voltages outside this range could damage the LP3500.
Reset switches are located on both sides of the LP3500 board.

NOTE: Do not connect the AC adapter to the VBAT terminal on the Prototyping Board.
NOTE: A hardware reset may be done by pressing the RESET switch on the LP3500.
The VBAT terminal supplies the backup battery voltage of 3 V, and the LP3500 may be
damaged if subjected to the raw DC voltage from the AC adapter through the VBAT
terminal.
The LP3500 may also be reset by unplugging the AC adapter, then plugging it back in.
However, when the LP3500 is operating in the power-save mode, the backup battery
will provide sufficient voltage to prevent a reset from happening, in which case you will
have to press the RESET switch on the LP3500.
