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 that the continuous DRAIN voltage waveform may be
observed. It is recommended that the V
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. Temporarily
shorting the CONTROL pin to the SOURCE pin will reset
TOPSwitch, which then will come up in the correct state.
