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. Guaranteed by characterization. Not tested in production.

C. For externally adjusted current limit values, please refer to the graph (Current Limit vs. External Current Limit Resis-

tance) in the Typical Performance Characteristics section.

D. It is possible to start up and operate TOPSwitch-FX 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 for low voltage operation characteristics.
