For specifi cations with negative values, a negative temperature coeffi cient corresponds to an increase in
magnitude with increasing temperature, and a positive temperature coeffi cient corresponds to a decrease in
magnitude with increasing temperature.
Guaranteed by characterization. Not tested in production.
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 specifi ed is only valid at full current limit.

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.
Breakdown voltage may be checked against minimum BV
