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.
B. Guaranteed by characterization. Not tested in production.
C. For externally adjusted current limit values, please refer to Figure 55 (Current Limit vs. External Current Limit
Resistance) in the Typical Performance Characteristics section.
D. It is possible to start up and operate
TOPSwitch-GX
at 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.
