Z-World Fox LP3500 User Manual page 30

When the LP3500 is connected to the Proto-
typing Board, a 0 Ω resistor on the Prototyp-
ing Board (R1) ties +K to VIN, the raw DC
input voltage. Figure 12 shows the location
of this 0 Ω resistor on the Prototyping Board.
NOTE: R1 on the Prototyping Broad
must be removed to avoid damage to
the power supplies if you are using the
Prototyping Board with the LP3500
and you are using separate power sup-
plies for VIN and K.
When the LP3500 is used alone, remember to connect a power supply to +K (pin 12 on
header J7). Your +K supply may be up to +36 V DC, and should be capable of delivering
up to 2.0 A.
NOTE: If +K is not connected, the digital inputs may float, which may increase your cur-
rent consumption.
