AC/DC Buck, Buck-Boost, Flyback Converter, LinkSwitch-TN2, 85 Vac to 265 Vac,360 mA, SOIC-8Product OverviewLinkSwitch-TN2 highly energy efficient off-line switcher IC with integratedsystem level protection for low component-count power supplies of ICs fornon-isolated off-line power supplies provides dramatically improved performancecompared to traditional linear or cap-dropper solutions. Designs using thehighly integrated LinkSwitch-TN2 ICs are more flexible and feature increasedefficiency, comprehensive system level protection and higher reliability. Thisfamily supports buck, buck-boost and flyback converter topologies. Each deviceincorporates power MOSFET, oscillator, on/off control for highest efficiency atlight load, high-voltage switched current source for self-biasing, frequencyjittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown,output and input overvoltage protection circuitry onto a monolithic IC.Applications includes appliances, metering, smart LED drivers, industrialcontrols, IOT, home and building automation.Output current of 225mA (MDCM), 360mA (CCM) at 230VAC and 225mA (MDCM), 360mA(CCM) at 85-265VACHighest performance and design flexibility EcoSmart extremely energy efficientEnhanced safety and reliability features, auto-restart for short-circuit andopen loop faultsOutput overvoltage protection, line input overvoltage and hystereticovertemperature protectionExcellent load and line regulation, 66KHz operation with accurate current limitAllows use of low-cost off-the-shelf inductors, reduces size and cost ofmagnetics/output capacitor725V MOSFET rating for excellent surge withstand, pin-out simplifies PCB heatsinkingExtended creepage between DRAIN pin and all other pins improves fieldreliabilityStandby supply current
