Original question:

TMS320F28379D: TMS320F28379D

TMS320F28379D: TMS320F28379D

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE, TMDSCNCD28379D, TMDSHSECDOCK,

I have been trying to get exact dimensions and exact interconnecting pad locations of the Delfino control card.

In the document, there is a circular self-reference: i.e., one can read

The following PDF documents are provided to describe where each of the F2837x MCU’s pins will appear
on the controlCARD connector/docking station:
• TTMDSCNCD28379D_180cCARD_pinout_R1_3 – tells where each MCU pin will go on the HSEC
controlCARD connector or the 120/180-pin controlCARD docking station.

But if you click on the referenced link, or find the document,  it brings you back to this document!

So where can I find documents to study the interconnect pins, pinouts on the control card including its geometry? Our immediate intention is to hook it to  our demo hardware & start demo/edit modify code etc.

Also, it is gaining time: by the time we get the control card/ baseboard, signal injector, we would have made progress about interconnecting them.A related matter is : should we get the Launch pad as well with the docking card/control card& the injection card? 

Appreciate pointing out where the information can be found..

    Robin,

    I just received your question, should have the answer for you tomorrow.

    Robin,

    you have a lot of questions in this post, so my answer might get a bit messy.

    The gerbers are provided in C2000Ware, these should provide all spatial dimensions. Additionally the following post provides some information(the first and last pins are 21mm OC) : https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/530337/2074532#2074532

    I do not see any links to this document.

    The aforementioned document has a small typographical error, it should be "TMDSCNCD28377D_180cCARD_pinout_R1_3.pdf". I have submitted a bug for this to be updated.

    Finally the document named "TMDSCNCD28377D_180cCARD_pinout_R1_3.pdf" is not a circular reference and can be found in C2000Ware: C:\ti\c2000\C2000Ware_x_xx_xx_xx\boards\controlCARDs\TMDSCNCD28379D\R1_3.

    Are you having difficulties procuring a controlCARD? It should be available through any of the following links.

    1. http://www.ti.com/tool/TMDSDOCK28379D
    2. https://www.digikey.com/product-detail/en/texas-instruments/TMDSDOCK28379D/296-46778-ND/7219406

    What application are you trying evaluate? LaunchPads are low cost and show off the device well. However sometimes, depending on the application, a controlCARD makes more sense as it brings out more device pins and features.

    For generic device evaluation a F2837x LaunchPad or a F2837x controlCARD+TMDSHSECDOCK will work well. Supported application kits can be found here: http://www.ti.com/microcontrollers/c2000-real-time-control-mcus/design-development.html#application

    It is unclear what you mean by "injection card".

    Hope it helps,
    Cody

    First of all, thank you for your effort in reading through my issues & finding the answers.

    #2 is that they have shipped our buys: the Delfino control card+ dokcing stn, launchapd, and signal injection card for testing ADC performance. We should be getting them Thursday.

    #3 I am hoping all issues will be resolved then! Because, I suspect that websites do not show up the same way everywhere. That means that - in my PC- which is controlled by who knows who- there is no way I can locate gerbers for Delfino control  card...most designs ( those that are expected to be reproduced) do have all design items clearly posted- but not for Delfino. For example, I can quickly locate Delfino based LLC design materials,  provided you know how to search for it. But  sch, gerbers, BOM etc are found very easily in one place.

    Not for Delfino control card we have in mind.

    Allow me to ping you again if the shipping does not have documents from which we can know intended dimensions, pinout definitions etc.

    Cody:

    By bullheadedness here, I rummaged through my own saved documents: because I was sure we selected Delfino the moment we saw a ref design using it for LLC. We have one exact power  different voltage.

    I am attaching the document here for convenience - mostly because I failed to get a search result in the TI website using all  key words I used before.....

    So the big clarifying question is: in the schematic TID1001_sch/controller,does it  not reference the TMS320F28379D control card we are about to receive today?

    It looks like it does : if you see the 3 segments of edge connectors- one set of 28( left )x2, 2nd segment of another 28(mid)x2, and third segment( right)...they match. Although I need to see the control card schematic itself to make sure.

    They  give the signals at these pins.

    And the rest of the sch for LLC. 

    I am sure this is it.

    All we have to do now is to fit it in our our PFC  hardware & edit the code / add voltage mode loop without any current mode- & the rest follows.

    You think I am in the right direction here?

    thnx for all your support.tidrqc9_C2K_LLC_SCH.pdf

    Robin,

    TI designs have all of their schematics, gerbers, and other files in one place. That place is the on the Web page.

    All C2000 Core EVMs have all of their design files(schematics, gerbers and more) in one place too, but its not the web page. It is inside of C2000Ware. Download C2000Ware and then look in: C:\ti\c2000\C2000Ware_2_00_00_02\boards\controlCARDs\TMDSCNCD28379D 

    Unfortunately the TI.com search tool isn't that great, I usually go to google's "advanced search" and assign the "domain" to "www.ti.com".

    I think you're heading in the right direction, get the controlCARD's design files from C2000Ware and they should hopefully answer most of your questions. For convenience I've attached the schematic here(this is also in C2000Ware).

    Thnx again Cody.

    FedEx delivered all the parts we bought.

    But of course they stuffed in fliers that refer to the links that I have to go through google now on.

    Let the games begin.

    We are proceeding with the most daring endeavor ever: in one scoop from ignorance to dual core 2- converter control with all GaN!

    will keep you posted.

    Awesome!

    If you don't mind me asking, what is your end application?

    What topology that you are planning on using?

    And what GaN device are you planning on using?(LMG?)

    Thanks,
    Cody

    no problem: one will be HB LLC as described by the ref design using Delfino.

    The other one will be : fixed frequency resonant mode ac-dc. Basic topology is  Cuk's original. But some simple manipulation leads to an awesome bridgeless pfc.

    There are  pros & cons. With GaN, cons can be overcome.

    We have some LMG3410, some NV6117 , EPC3024, GS66508 of course. Lots of Gan. 3 ph 400 Hz input, max going to 180V per phase,  have resonant peak voltage/current are rather high. But all switches have ZVS. To get high power, we put  lot of these in parallel. Hence intense interest in digital control.

    It wont work without that & small GaN footprint.
