NOTES:
A. Derived during test from the parameters DC MAX , I B and I C(OFF) at 132 kHz.
B. 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.
C. Guaranteed by characterization. Not tested in production.
D. For externally adjusted current limit values, please refer to Figures 36 and 37 (Current Limit vs. External Current Limit Resistance)
in the Typical Performance Characteristics section. The tolerance specified is only valid at full current limit.
E. I 2 f calculation is based on typical values of I LIMIT and f OSC, i.e. I LIMIT(TYP)2 × f OSC , where f OSC = 66 kHz or 132 kHz depending on F pin
connection. See f OSC specification for detail.
F. The device will start up at 18 V DC drain voltage. The capacitance of electrolytic capacitors drops significantly at temperatures below
0 °C. For reliable start up at 18 V in sub zero temperatures, designers must ensure that circuit capacitors meet recommended
capacitance values.
G. Breakdown voltage may be checked against minimum BV DSS specification by ramping the DRAIN pin voltage up to but not exceeding
minimum BV DSS .
