Power Integrations (TOP256EN) AC/DC Off-Line Switcher IC, TOPSwitch-HX

AC/DC Off-Line Switcher IC, TOPSwitch-HX, Flyback, 85 VAC - 265 VAC, 66 kHz, 4.08 A out, 119W, SIP-7 Product Overview The TOP256EN is an enhanced EcoSmart™, Integrated Off-line Switcher with 30W peak, advanced feature set and extended power range. TOPSwitch-HX cost effectively incorporates a 700V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device. Multi-mode operation maximizes efficiency at all loads Low thermal impedance junction-to-case (2°C per watt) Low height is ideal for adapters where space is limited Simple mounting using a clip to aid low cost manufacturing Line under-voltage (UV) detection prevents turn-off glitches Line overvoltage (OV) shutdown extends line surge limit Accurate programmable current limit Optimized line feed-forward for line ripple rejection Half frequency option for video applications Frequency jittering reduces EMI filter cost Heat sink is connected to SOURCE for low EMI Fully integrated soft-start for minimum start-up stress Energy efficient over entire load range Less than 200mW at 230VAC, no load consumption Standby power for 1W input Applications Power Management, Consumer Electronics Product Information Input Voltage AC Min: 85V Input Voltage AC Max: 265V AC / DC Converter Case Style: SIP No. of Pins: 7Pins Power Rating: 119W Topology: Flyback Operating Temperature Min: -40°C Operating Temperature Max: 150°C Product Range: TOPSwitch-HX Series
