NOTES:
A. 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.
B. Breakdown voltage may be checked against minimum BV
DSS
specification by ramping the DRAIN pin voltage up to but not
exceeding minimum BV
DSS
.
C. I
is increased gradually to obtain maximum current limit at di/dt of 90 mA/
μ
s. Increasing I
C
further would terminate the cycle
through duty cycle control.
D. This parameter is normalized to I
DCT
to correlate to power supply output current (it is multiplied by I
DCT
(nominal)/I
DCT
).
E. It is possible to start up and operate
LinkSwitch
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 the characteristic
graph on CONTROL pin charge current (I
C
) vs. DRAIN voltage (Figure 13) for low voltage operation characteristics.
