NOTES:
A. For specications with negative values, a negative temperature coefcient corresponds to an increase in
magnitude with increasing temperature, and a positive temperature coefcient 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 Figures 54b, 55b and 56b (Current Limit vs. External
Current Limit Resistance) in the Typical Performance Characteristics section. The tolerance specied is only valid
at full current limit.
D. Breakdown voltage may be checked against minimum BV
DSS specication by ramping the DRAIN pin voltage up
to but not exceeding minimum BV
DSS.
E. 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 68, the characteristic graph on CONTROL pin charge current (I
C) vs. DRAIN voltage for low
voltage operation characteristics.
