Application note
35 W wide-range high power factor flyback converter
demonstration board using the L6562A

Introduction
This application note describes a demonstration board based on the transition-mode PFC
controller L6562A, and presents the results of its bench demonstration. The board is a 35 W,
wide-range mains input, power factor corrected SMPS (switched mode power supply)
suitable for all low power applications requiring a high PF (power factor), such as lighting
applications and power supplies for LEDs. The low-
