I tried it! No use, no answer.
Friends can someone come across and tell me? What is the frequency of the control and synchronization pulses at the output 8 of the pic16f818 microcontroller....

Thanks, I'll try....

Good evening colleagues!
After purchasing the digital voltage converter Riden rd6018w module, I decided not to purchase a power supply for it, but to restore the non-working FNP1500-48G, which I got a few years ago and power the converter with it. But I cannot restore it due to the lack of firmware for the pic16f818 microcontroller, which is responsible for the operation of the PFC and the synchronization of the MOSFET control drivers, as well as protection for flow and temperature.
The reason for the failure of the Power-one FNP1500-48G power supply was damage to the MOSFET transistors,...
