TPS63060-EP: Maximum reverse current

Hi  Danilo,

i think you can find the maximum reverse current when Vin is 5V in datasheet, it is 900mA. also, you can find the transient time in datasheet too.

so, any other concern about your problem?

Hi Tao,

Thank you for your response. It seems that the datasheet you are pertaining to is the catalog version of TPS63060. Our customer's inquiry is for the enhanced version, TPS63060-EP. I have searched these information from the datasheet of TPS63060-EP but they are not available. Please refer to the datasheet below for our common reference.

Are the maximum reverse current and transient time the same for catalog and enhanced products?

Hi  Danilo,

that is right, my apologize.I did not notice we have a EP version at all.

Comparing these two chips, it looks like they are quite different and i am not sure the circuit about reverse current limit and Ttransent internal changed or not. so i think i have to ask design team and there will be a big delay. worst, may be design do not have answer too.

if customer has devise on hand, how about do some bench test to check it out and keep some margin in actual case?

my side, i will try to find some chip and do some bench to confirm.

Hi Tao,

Thank you for your feedback. I will check if the customer has some devices on hand, however, how can they test the maximum reverse current and transient time? Do we have any test procedure for these kinds of tests?

Danilo

Hi Tao,

I have forwarded the test procedure to our customer and waiting for his feedback if he has a device on hand to test. May I confirm if our design team have provided the information that our customer had requested?

Hi  Danilo,

not yet for they have not back to office. i think they will reply next week and i will let you know if i got any update.

Hi   Danilo,

bad news from my side. i still got no response from design team and i can not find any TPS63060-EP in shanghai office.

so how is it going on your side?
