I took the L6565 application sheet circuit and replaced the L6565 with a PIC16f506.
It basically seems to work ok with two exceptions.
1/ On high power the transformer whistles very loudly.
2/ The transformer seems to get hot.
The PIC provides the mosfet pulse. It also looks at the winding for...
I have taken a l6565 circuit and replaced the l6565 with a PIC micro.
On the output of the transformer I ma getting a lot of ringing.
Does anyone know how to get rid of this ?

I have taken an L6565 circuit and used a PIC instead to generate 50KHz pulses to the transformer via a mosfet driver and mosfet.
Does any one for see any problems doing this ?
I forgot to gap the transformer and blew my fuses.
Are there any other problems that might occurr ?
