Hi everyone,
I am using UCD9222+UCD7242 for power supper to TMS320C6678,the power output should be 1v and 0.9v . the configure is just like the UCD9222 configure project in 6678evm.but when I active the power output,the result is wrong.as I know ,the duty cycle should be 1/12.but the result is more than 20%,why?any advise will be nice,thank you .
Hello Guoping Lee,
Where can i get the configuration file for the 6678evm
Thanks
Ashok
Hi Ashok
you can download the UCD9222 configuration from http://www.advantech.com/Support/TI-EVM/6678le_download3.aspx.
Thank you Lee, by the way did you get the UCD9222 issues solvedÉ
not yet .Do you have any idea?
Hi Lee,
I am just going to use these ICs on my board which is still in design phase. So i donot have any results now.
Any way from the graphs, not only the duty cycle is strange, even the output voltage is swinging until 2V. Does these graphs depict correctly what you see on your board when you probe it (output voltage and duty cycle)?
