Typical Performance Characteristics
The following precautions should be
followed when testing TOPSwitch by
itself outside of a power supply. The
schematic shown in Figure 14 is
suggested for laboratory testing of
TOPSwitch.
When the DRAIN supply is turned on,
the part will be in the auto-restart mode.

The control pin voltage will be oscillating
at a low frequency from 4.7 to 5.7 V and
the DRAIN is turned on every eighth
cycle of the CONTROL pin oscillation.
If the CONTROL pin power supply is
turned on while in this auto-restart mode,
there is only a 12.5% chance that the
control pin oscillation will be in the
correct state (DRAIN active state) so

recommended that the V
be turned on first and the DRAIN power
supply second if continuous drain voltage
waveforms are to be observed. The
12.5% chance of being in the correct
state is due to the 8:1 counter.
