TOP单端反激设计范例 发电源资料(反激篇)
This document is an engineering report that describes a universal input power supply that utilises a TOP249Y. This supply is an off-line flyback converter that operates in continuousmode.Belowisalistofnotablefeatures:
• Verycompactdesign:(4.1”×2.25”×1.06”internalboxdimensions)
• Highpowerdensity-7W/inch³
• Fulloutputpowerinsealedenclosureat40°Cambient
• Highefficiency:84%(85VAC),89%(230VAC)
• Lowno-loadconsumption:350mW(115VAC),500mW(230VAC)
• Lowvalueinputcapacitor:extendedmaximumdutycycleallows2µF/W
