Application note
35 W wide-range high power factor flyback converter evaluation
board using the L6562A
Introduction
This application note describes a product evaluation 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-cost L6562A and the simple flyback
topology combine to provide a very competitive PFC controller solution.
