Other Parts Discussed in Thread: LM5122
We currently have a multi-phase boost using two LM5122. The circuit will boost the input voltage of 9-48V to 48V.
This works perfectly and no issues thus far.
Our customer requirements have changed and we need to convert our non-isolated setup to an isolated setup.
Having issue dialing in the right components. I understand the design changes needed but im not understanding the flyback transformer.
I haven't been able to find a component which meets my requirement. There will be around 5-6 amps going through each phase.
What I have been finding are flyback transformer with a output voltage spec of 5 or 12V. Or I am finding ones that give a 1:3 turn ratio but since I have a variable input voltage I don't believe these will work, as it would lead to over voltage.
Am i missing something when converting to an isolated setup? I am thinking I need a flyback transformer with a 1:1 ratio and can handle the current.
Trying to design a 480W multi-phase isolate supply using the LM5122. Assuming 5A current per flyback.
Any tips on the proper way to convert this design to isolated?
Also the inductance of the flyback transformer / planar transformer. Right now the design has two 22uh inductors. We moving to an isolated configuration would the inductance of the transformer be the same?
