TOP258PN TOP258P POWER DIP7

Off-Line Switcher with Advanced Feature Set and Extended Power Range

Lower System Cost, Higher Design Flexibility Multi-mode operation maximizes effi ciency at all loads No heatsink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset Allows both primary and secondary sensing

Energy effi cient over entire load range No-load consumption <200 mW at 265 VAC Standby power for 1 W input >600 mW output at 110 VAC input >500 mW output at 265 VAC input Description TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
