Note that there is a DC path in the boost converter from the
input to the output through the inductor and diode, hence the
input voltage will be seen at output with a forward voltage
drop of diode before the part is enabled. If this voltage is not

desired, the following circuit can be inserted between input
and inductor to disconnect the DC path when the part is
