BENCH TEST PRECAUTIONS FOR EVALUATION OF ELECTRICAL CHARACTERISTICS
The following precautions should be followed when testing
TOPSwitch by itself outside of a power supply. The schematic
shown in Figure 11 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.
