Power Integrations (TOP227YN) AC / DC Converter, Boost, Buck, Flyback

AC / DC Converter, Boost, Buck, Flyback, Forward, 85 to 265 VAC, 90 W, TO-220-3,-40 °C to 150 °CProduct OverviewThe TOP227YN is a second generation, TOPSwitch-II three terminal off line PWMswitch in 3 pin TO-220 package. It is a lowcost and lowest component countswitcher solution. Many significant circuit enhancements that reduce sensitivityto board layout and line transients make the design easier. TOPSwitch-II familyis more cost effective and provides several enhancements over first generationTOPSwitch family. It incorporates all functions necessary for switched modecontrol system into three terminal monolithic IC. The TOP227YN has built-in autorestart and current limiting features. It works with primary or opto feedback.The circuit simplicity and design tools reduce time to market. This PWM switchimplements flyback, forward, boost or buck topologies. It integrates the highvoltage power MOSFET, PWM control, fault protection and other control circuitryonto a single CMOS chip.Output power of 150W at 100/115/230VAC single voltage input and 90W at 85 to265VAC wide inputOutput frequency of 100KHzDuty cycle range from 1.7% to 67%Drain supply voltage of 36VCost competitive with liners above 5WVery low AC/DC losses and up to 90% efficiencyLatching thermal shutdown for system level protectionStable in discontinuous or continuous conduction modeSource connected tab for low EMIOperating junction temperature range from -40°C to 150°CApplicationsConsumer Electronics, Portable Devices, Audio, Power Management, MultimediaProduct InformationInput Voltage AC Min: 85VInput Voltage: 265VOutput Voltage: 700VInput Voltage AC Max: 265VAC / DC Converter Case Style: TO-220Output Current: 300mANo. of Pins: 3PinsSupply Voltage Min: 36VSupply Voltage Max: 36VPower Rating: 90WTopology: Boost, Buck, Flyback, ForwardOperating Temperature Min: -40°CFrequency: 100kHzOperating Temperature Max: 150°CProduct Range: TOPSwitch-II Series
