The following precautions should be followed when testing

TOPSwitch-GX by itself outside of a power supply. The sche-

matic shown in Figure 53 is suggested for laboratory testing of

TOPSwitch-GX.

When the DRAIN pin supply is turned on, the part will be in

the auto-restart mode. The CONTROL pin voltage will be

oscillating at a low frequency between 4.8 and 5.8 V and the

drain is turned on every eighth cycle of the CONTROL pin

oscillation. If the CONTROL pin power supply is turned on

Typical Performance Characteristics

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 wave-

form may be observed. It is recommended that the V

C power

supply be turned on first and the DRAIN pin 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 divide-by-8 counter. Temporarily shorting the

CONTROL pin to the SOURCE pin will reset TOPSwitch-GX,

which then will come up in the correct state.
