NOTES:

1. 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.

2. It is possible to start up and operate TOPSwitch at DRAIN voltages well below 36 V. However, the CONTROL pin

charging current is reduced, which affects start-up time and auto-restart frequency and duty cycle. Refer to the

characteristic graph on CONTROL pin charge current (I ) vs. DRAIN voltage for low voltage operation
