Greetings.
I am building a 24V, 240W power supply with the help of the ST eDesign Suite website. The problem I have is that before starting, it goes into a blinking mode. To start it, I have to measure with a multimeter on the ZCD pin. Then, suddenly, it enters the steady state and outputs a continuous voltage value. Before this, the Vcc voltage has a triangular shape in the power supply, reaching the minimum supply value of 10.4V and 12.5V.
Would anyone know what this is due to and how I can fix it?
I was wondering if it would be possible to obtain the Spice model to simulate the component.
Attached is the link to view the power supply design in eDesign Suit: L6566B QR FLYBACK AC/DC Converter | eDesignSuite | STMicroelectronics
I have also used two different transformers in case the problem was this. I am attaching them as well.
Greetings and thank you very much.
