TPS92611-Q1: 1. Impulse noise test setup 2. simulation LED in output

Hi Roy,

i want more information about this case:

1) please describe the test standard, i can't figure out from the description “fail”;

2)please describe the test set up as detail as possible;

3) please describe the phenomenon of the fail, and how u judge fail with non-LED load;

4)LED's feature is different from E-load, so i recommend you use LED to test;

1) please describe the test standard, i can't figure out from the description “fail”;

As image, the test is using the coil in Vout(+) to LED wire and inject a noise showing as image. Fail means there is no Vout for TPS92611. 

2)please describe the test set up as detail as possible;

As above.

3) please describe the phenomenon of the fail, and how u judge fail with non-LED load;

my question1 and question2 is different question. question1 is using LED and test the application by previous image.

4)LED's feature is different from E-load, so i recommend you use LED to test;

As above.

Roy

For your 1 question: i think the test is over spec, TI also have some solution for ESD protect to pass relevant level.

For your 2 question: you can use CV mode to simulate.

Hi Frank,

Could you help suggest ESD solution to pass the the test?

Roy

Does this part meet the requirement?
