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 °C Product Overview The TOP227YN is a second generation, TOPSwitch-II three terminal off line PWM switch in 3 pin TO-220 package. It is a lowcost and lowest component count switcher solution. Many significant circuit enhancements that reduce sensitivity to board layout and line transients make the design easier. TOPSwitch-II family is more cost effective and provides several enhancements over first generation TOPSwitch family. It incorporates all functions necessary for switched mode control system into three terminal monolithic IC. The TOP227YN has built-in auto restart and current limiting features. It works with primary or opto feedback. The circuit simplicity and design tools reduce time to market. This PWM switch implements flyback, forward, boost or buck topologies. It integrates the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Output power of 150W at 100/115/230VAC single voltage input and 90W at 85 to 265VAC wide input Output frequency of 100KHz Duty cycle range from 1.7% to 67% Drain supply voltage of 36V Cost competitive with liners above 5W Very low AC/DC losses and up to 90% efficiency Latching thermal shutdown for system level protection Stable in discontinuous or continuous conduction mode Source connected tab for low EMI Operating junction temperature range from -40°C to 150°C Applications Consumer Electronics, Portable Devices, Audio, Power Management, Multimedia Product Information Input Voltage AC Min: 85V Input Voltage: 265V Output Voltage: 700V Input Voltage AC Max: 265V AC / DC Converter Case Style: TO-220 Output Current: 300mA No. of Pins: 3Pins Supply Voltage Min: 36V Supply Voltage Max: 36V Power Rating: 90W Topology: Boost, Buck, Flyback, Forward Operating Temperature Min: -40°C Frequency: 100kHz Operating Temperature Max: 150°C Product Range: TOPSwitch-II Series
