This document describes an 11W Switch Mode Power Supply reference design, dedicated to Consumer
Applications, e.g. TV chassis auxiliary power supply, low cost Set-top box or digital equipment. The
board accepts full range input voltage (90 to 265Vrms) and delivers 2 output voltages. It is based on the
monolithic controller L6590, integrating the controller and a POWERMOS and working at fixed frequen-
cy, PWM mode and
