TOPSwitch-HX family enhanced EcoSmart, integrated off-line switcher with advanced feature set and extended power range. TOPSwitch-HX cost effectively incorporates 700V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device. It is a highly integrated monolithic off-line switcher IC designed for off-line power supplies. TOPSwitch-HX integrated circuits enable design of power supplies up to 195W, while providing high efficiency under all load conditions. Also provides very good performance at low load and during standby (no load) operation. TOPSwitch-HX allows designer to meet efficiency requirements for new energy efficiency standards. Applications includes LCD monitor, personal computers, small servers, laptop adapters, set-top boxes, digital TVs, printers, DVD players and recorders, UPS, video games, broadband modems, cellular phone adapters and audio amplifiers.
