The following precautions should be followed when testing
TOPSwitch by itself outside a power supply. The schematic
shown in Figure 12 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 that the continuous DRAIN voltage waveform
may be observed. It is 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.
