PMP20637: PMP11432

Part Number: PMP20637

Pl see attached pdf that highlights primary current  used in the UCD3138 control card.

But where is this IPS generated? In the C2000, FB-LLC, one has a clear circuit in the primary and labels that can be tracked all the way from primary to the control card.

In a similar manner, which HB-LLC design would have generated IPS & with what filtering as a design guide?

It is not in any of the tidrn80, tidrn82 & tidrn83

Any help will be highly appreciated.

Our roadblock right now is that we do not seem to pin down our GaN HB-LLC with split capacitor provides  all signals UCD3138 control card expects &  also can receive all signals the control card sends for proper control.

We need to proceed to routing asap.PMP11432_IPS_ROOT.pdf

  • Robin,

    The IPS node was for primary current sense for my other LLC reference designs (For example: PMP20289) with TI GaN devices, but it is not being used in PMP20637 design as TI GaN device provides reliable over current protection already. The PMP11432 control card is used in many projects. Sorry to confuse you with the node naming.

    I assume you already got what you need in the other thread you sent. I will close this thread.
