LM34927：LM34927multi-channel isolated output

keven D

Part Number: LM34927

I want to use the isolated output of LM34927 to achieve multi-channel isolated output of the same voltage value through multi winding transformer, with light load and single peak value of about 50ma. Is it feasible to take three to four isolated outputs

Hi Keven,

It might technically be possible, but it's going to be a bit more complicated to generate the needed amount of ripple for the feedback mechanism to function. It also depends on what voltage you need the secondary sides to be. Lastly, you might want to leave an area to populate some resistors as the flyback may need some minimum current in order to function.

You can mess around with this tool and see if it helps.
