NOTES:

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.

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 speciﬁed is only valid at full current limit.

I2f calculation is based on typical values of I

LIMIT and fOSC, i.e. ILIMIT(TYP)

2 × f

OSC, where fOSC = 66 kHz or 132 kHz depending on package

/ F pin connection. See f

OSC speciﬁcation for detail.

The TOPSwitch-HX will start up at 18 V

DC drain voltage. The capacitance of electrolytic capacitors drops signiﬁcantly at tempera-

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

DSS speciﬁcation by ramping the DRAIN pin voltage up to but not

exceeding minimum BV

DSS.
