B. Guaranteed by characterization. Not tested in production.
D. Breakdown voltage may be checked against minimum BV
DSS
specification by ramping the DRAIN pin voltage up to
but not exceeding minimum BV
DSS
.
E. It is possible to start up and operate TOPSwitch-GXat DRAIN voltages well below 36 V. However, the
CONTROL pin charging current is reduced, which affects start-up time, auto-restart frequency, and auto-restart
duty cycle. Refer to Figure 67, the characteristic graph on CONTROL pin charge current (I
C
) vs. DRAIN voltage
for low voltage operation characteristics.

NOTES:
A. For specifications with negative values, a negative temperature coefficient corresponds to an increase in
magnitude with increasing temperature, and a positive temperature coefficient corresponds to a decrease in
magnitude with increasing temperature.
C. For externally adjusted current limit values, please refer to Figure 54b and 55b (Current Limit vs. External Current
Limit Resistance) in the Typical Performance Characteristics section. The tolerance specified is only valid at full
current limit.
