Reverse Voltage Protection
Reverse voltage protection prevents damage due to the
output voltage being higher than the input voltage. This
fault condition can occur when the output capacitor remains
charged and the input is reduced to zero, or when an
external voltage higher than the input voltage is applied to
the output side.

If the control function is not used, connect the control
terminal to V
IN
. When the control function is used, the
control current can be reduced by inserting a series
resistor (R
CONT
) between the control terminal and V
IN
. The
value of this resistor should be determined from the graph
below.
