Electrical performance

With the circuit used in this evaluation board, when the output current has rapid variation
from maximum to zero and the input voltage is low ( < 105 V
supply for about 400-500 ms. The output voltage thereby decreases. After that time the IC
turns on again and the output returns to the nominal value. This behavior is not problematic
in this kind of application and has not been modified, in order to have a smaller and cheaper
solution. If this phenomenon must be avoided, however, it is enough to increase C3 to
100 µF.
