TIDA-01604: G184014LF

TIDA-01604: TIDA-01604 and TIDA-01605

Part Number: TIDA-01604
Other Parts Discussed in Thread: TIDA-01605, UCC21521, UCC21520, UCC21530

Hello again.

i would like to ask you some questions regarding the TIDA-01604 and TIDA-01605:

1. What control card is used in the reference design in your PDF? Is it possible the code to be different for the card used in your make up and if i use the suggested 280049C control card?

2. Is it possible to have some error in the shematic for the 01605??? For exapmle can you confirm the D5 orientation? Also The picture for U6 IC in your pfd is UCC21521, but the label bellow the picture is UCC21520. Now i have two other questions: what is correct to have on the EN pin of the chip? 1 or 0? What R configuration to use? R30, R32 R31 ??? I am using UCC21520 and as we can see on page 3 here https://www.ti.com/lit/ds/symlink/ucc21520-q1.pdf it is with disable pin (not enable as in your pdf)

3. Do you have any updated files for this design? 

I have spend alot of time and money for this project, but it is still not working and i am wondering what is your oppinion regarding any software changes i have to do in order to make it work with 280049C control card.

Thanks in advance!

Best regards,

Dan

    Hi Dan,

    1, the program downloaded form PDK is compatible with F280049C, we used this one for the test.

    2, The U6 IC in the PDF should be UCC21520 but pin 5 is wrong, it should be "DISABLE". Both UCC21521 (UCC21530) and UCC21520 can be used, but their pin 5 logic is different, solder R30&R32 if using UCC21520, solder R31 if using UCC21521(UCC21530).  We will update the document, sorry for the confusion.

    3, we will update the design by replacing driver as UCC21530 ( removed pin 12&13 from UCC21521 for more channel-to-channel spacing). For the software part, it should work with F280049C without any change. 

    When you say board is not working, could you check the driver part first to see if there is PWM with open loop test? 

    Regards,

    Hi Gangyao,

    now i soldered the R30&R32. Once i test the PWM with open loop test it is working fine.

    If i try to test with Closed current Loop DC and the timer goes to 100, there is a error and the board is disconnected. The error says "Break at address "0x3fb02a" with no debug information available, or outside of program code"

    What can be the reason? Any suggestions?

    Best Regards,

    Dan

    You have an issue with power, the power dip is causing JTAG to be lost.

    what is the current limit of the power supply you have connected for 5.2V ? It should be 2Amps,

    Dear Manish,

    my current limit is set to 9Amps.

    If i try to test with 220V AC then it goes to 660V DC and then it switch off and its state is "OverVoltageProtection"

    I will not recommend a previously unknown board directly with 220VAC, we provide incremental builds to validate the hardware so issues under assembly and build can be localized and identified.

    So based on the above comment, you are saying that the DC build went ok?

    Yordan did the answers previously provided by the Texas Instruments team work such that your build/design worked okay? Please let us know.
