Drain Voltage (V)

VC = 5 V

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

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.

BENCH TEST PRECAUTIONS FOR EVALUATION OF ELECTRICAL CHARACTERISTICS

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.
