EVL6564-50WFLB 50 W wide range high power factor flyback converter demonstration board based on the L6564
The EVL6564-50WFLB demonstration board implements a 50 W, wide-range mains input, power factor corrected, power supply suitable for all low power applications needing a high PF, such as lighting applications, LED power supplies, etc. It is possible through the use of a low-cost device like the L6564 united with a simple topology like the flyback one, providing, therefore, a very competitive solution.
The main feature of this converter is that the input current is almost in phase with the mains voltage; therefore the power factor is close to unity. This is achieved by the controller, the L6564, shaping the input current as a sinewave in phase with the mains voltage
