I'm looking for a smart solution to realize a AC/DC converter
with these main spec:
Vin = 230Vac@50Hz
Vout = 10V Isolated
Iout = 0.3A
Main targets of the design are:
- Small dimension:
now I've a solution with a 60KHz flyback on a 30x30mm PCB with a
20x20x15mm transformer, but is still too big (mainly the transformer).
- Cost and availability of components.
- The converter must not switch in the 70-190KHz range.
Do you have any PowerInt solution for this issue?
Maybe with an higher switching freq or a different topology (forward, push-pull,..)?
