Keywords:switch mode power supply? power supply? controller? quasi resonant mode?

This document from STMicoelectronics describes a reference design for a 17W switch mode power supply dedicated to STB applications. The board accepts European input voltage (185-265Vac) and delivers 6 outputs. With minor changes, the board is suitable for U.S. input voltage (88-135Vac). The power supply is based on the primary controller L6565, working in quasi resonant mode.
