• Manufacturer Part Number: top209
• Description: Three-terminal Off-line Pwm Switch
• Manufacturer: Power Integrations, Inc.

NOTES:
A. For specifications with negative values, a negative temperature coefficient corresponds to an increase in magnitude
B. The breakdown & leakage measurements can be accomplished by using the TOPSwitch auto-restart feature. The

with increasing temperature, and a positive temperature coefficient corresponds to a decrease in magnitude with
increasing temperature.
divide-by-8 counter in the auto-restart circuitry disables the output MOSFET from switching in 7 out of 8 cycles. To
place the TOPSwitch in one of these cycles, the following procedure can be carried out using the modified circuit of
