Dear Staff of Power Integrations,
Why does PI Expert always implement every flyback as a DCM flyback?
I did an 8V, 6A flyback in the PI Expert software and it did it as DCM. The secondary peak current came out as 26 Amps. At peak current levels like this, surely it would be better to use a CCM design?
If it had been done with a CCM design, the secondary peak current could have easily been reduced to 9.7 Amps.
The flyback spec was:-
Vout = 8v
Iout = 6A
Fsw = 66khz
Vin = 85-265VAC
