NOTES:
A. For specifications with negative values, a negative temperature coefficient corresponds to an increase in magnitude with increas-
ing 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 Figures 55a and 55b (Current Limit vs. External Current Limit Resis-
tance) in the Typical Performance Characteristics section. The tolerance specified is only valid at full current limit.
D. I f calculation is based on typical values of I
2
/ F pin connection. See f
E. The TOPSwitch-HX will start up at 18 V
tures below 0 °C. For reliable start up at 18 V in sub zero temperatures, designers must ensure that circuit capacitors meet
recommended capacitance values.
F. Breakdown voltage may be checked against minimum BV
exceeding minimum BV
