The following circuits are the test configurations that
were used to obtain the data for the graphical section of the
NCP1650/D data sheet. Each graph has a schematic
associated with it and in some cases a description of the
procedure.

Power up chip. Set IS– between 0 and –200 mV in 50 mV
increments. For each value of IS– set the ac input (pin 5) to
various values from 0 to 3.8 volts. Record output Pmax (pin 9).
