Power Integrations (TOP245PN) AC/DC Converter IC, 85 VAC - 265 VAC

AC/DC Converter IC, TOPSwitch-GX Family, Flyback, 85 VAC - 265 VAC, 22 W, DIP-7Product OverviewThe TOP245PN is an extended power design flexible EcoSmart® Integrated OfflineSwitcher uses the same proven topology as TOPSwitch, integrating the highvoltage power MOSFET, PWM control, fault protection and other control circuitryonto a single CMOS chip. Many functions are integrated to improve designflexibility, performance and energy efficiency. It is an integrated switchedmode power supply chip that converts a current at the control input to a dutycycle at the open drain output of a high voltage power MOSFET. During normaloperation the duty cycle of the power MOSFET decreases linearly with increasingCONTROL pin current. It incorporates many additional functions that increasepower supply performance and design flexibility. A patented high voltage CMOStechnology allows both the high voltage power MOSFET and all the low voltagecontrol circuitry to be effectively integrated onto a single monolithic chip.Extended power range for higher powerFully integrated soft-start for minimum stress/overshootExternally programmable accurate current limitWider duty cycle for more power, smaller input capacitorLine under-voltage detection - No turn-OFF glitchesLine overvoltage shutdown extends line surge limitLine feed-forward with maximum duty cycle reduction rejects line ripple andlimits DCMAX at lineFrequency jittering reduces EMI and EMI filteringRegulates to zero load without dummy loadingHalf frequency option in Y/R/F packages for videoHysteretic thermal shutdown for automatic fault recoveryLarge thermal hysteresis prevents PC board overheatingFrequency lowered with load for high standby efficiencyAllows shutdown/wake-up via LAN/input port132kHz Frequency reduces transformer/power supply size80mW at 110VAC, 160mW at 230VAC Extremely low consumption in remote OFF modeApplicationsPower Management, Imaging, Video & Vision, IndustrialProduct InformationInput Voltage AC Min: 85VInput Voltage AC Max: 265VAC / DC Converter Case Style: DIPNo. of Pins: 7PinsPower Rating: 22WTopology: FlybackOperating Temperature Min: -40°COperating Temperature Max: 150°CProduct Range: TOPSwitch-GX Series
