The circuit shown in Figure 1 allows for a single supply to be
used with a simple zenner diode regulation circuit to provide
the LM3410 with a housekeeping and driver voltage that is
below 5.5V.
The demonstration board provided can easily be modified to
allow the user to derive the power from an input supply that

The LM3410 VIN supply will draw approximately 7 mA while
it is switching. Zenner diode should have a breakdown voltage
lower than 5V, and size R3 to allow for 7 mA of current draw.
