Damith,
Lp is the primary winding inductance measured with secondary winding open.
Lr1 is the primary winding series/leakage inductance measured with secondary winding shorted.
Lr2 is the secondary winding series/leakage inductance measured with primary…
Kevin,
Take a look at https://www.ti.com/tool/PMP21999 This is an update to this design. I do believe the documentation needs a few updates, but PMP21999 shows the latest connections.
You are correct there was redundant isolation, That should have been removed…
Hi,
Yes, Cody is right. The published files are the latest one. the missing nets (breaking connection?) might be related to the transformer? This is because we are using flying leads to connect transformer and PCB.
And actually there is a new hardware…
