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

exceeding minimum BV

C. I

through duty cycle control.

D. This parameter is normalized to I

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
