TOP255PN (AC/DC Converters 22W )

Description

TOP255PN IC, OFF-LINE SWITCHER, 22/35W, 255 Product Overview 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. 19W (adapter), 30W (openframe) at 230VAC and 13W (adapter), 22W (openframe) at 85-265VAC O/P power Multi-mode operation maximizes efficiency at all loads, EcoSmart™- energy efficient Extended creepage between DRAIN and all other pins improves field reliability Frequency jittering reduces EMI filter cost, allows both primary and secondary sensing Line undervoltage (UV) detection prevents turn-off glitches Line overvoltage (OV) shutdown extend
