TOP202YAI (Power Integrations) is a three-terminal off-line PWM switch from the TOPSwitch family, with an integrated 700 V MOSFET and PWM controller, in a 3-pin TO-220 package.

• Low capacitance 700 V MOSFET and PWM controller with integrated 100 kHz oscillator · 70% maximum duty cycle
• Buck, boost, flyback or forward topology · interfaces with both opto and primary feedback
• Auto-restart and cycle by cycle current limiting · on-chip latching thermal shutdown
• 20 to 50 fewer components than a discrete solution · for 100/110/230 VAC off-line power supplies
