Power Integrations (TOP221PN) AC/DC Off-Line Switcher IC, TOPSwitch-II

AC/DC Off-Line Switcher IC, TOPSwitch-II Family, 85VAC - 265VAC, 100 kHz, 25 mAoutput, 6W, DIP-8Product OverviewThe TOP221PN is a 9W second generation 3-terminal Off-Line PWM Switch providesseveral enhancements over the first generation TOPSwitch family. Manysignificant circuit enhancements that reduce the sensitivity to board layout andline transients now make the design even easier. TOPSwitch incorporates allfunctions necessary for a switched mode control system into a three terminalmonolithic IC are power MOSFET, PWM controller, high voltage start up circuit,loop compensation and fault protection circuitry.Very low AC/DC losses up to 90% efficiencyBuilt-in auto-restart and current limitingLatching thermal shutdown for system level protectionWorks with primary or opto feedbackStable in discontinuous or continuous conduction modeSource connected tab for low EMICircuit simplicity and design tools reduce time to marketApplicationsConsumer Electronics, AudioProduct InformationInput Voltage AC Min: 85VInput Voltage AC Max: 265VAC / DC Converter Case Style: DIPNo. of Pins: 8PinsPower Rating: 9WTopology: Flyback, Forward, Boost, BuckOperating Temperature Min: -40°COperating Temperature Max: 150°CProduct Range: TOPSwitch-II Series
