UCD3138ACCEVM149: As the Training-lab only support UCD3138 rather than UCD3138A, I cannot realize the DTC function for SR

Hello,

 

I am wondering if you can help me? I am using UCD3138ACCEVM149 to develop program for a LLC circuit.

I have made a project that based on Training-Lab-1.0 Lab_03. 

after some modification to resonant mode, my UCD3138ACCEVM149 can output PWM signal 0.5~2MHz as my wish.

But, now there is a problem.

As the Training-lab only support UCD3138 rather than UCD3138A, I cannot realize the DTC function for SR. 

Becasuse even the registers of DTC were not defined in this program.

would  you please give me any suggestion?

or is there any simple example project that support UCD3138A?

thank you very much!

    There's no simple code for LLC.  It would be difficult to do one.  The LLC EVM code does have a version that cover DTC with UCD3138A.  When selecting the active configuration, select UCD3138a with Sunflower.  Sunflower is the name for the UCD7138 DTC interface/driver.  This is designed to work with the UCD.  The digital part of the DTC is implemented in the UCD3138 and the analog sections are in the UCD7138.  See the UCD7138 documentation for information on how it works.
