TPS2021: Turn on time

Hi John,

Sorry ,I don't know what you mean for Tset, is it the time delay between EN enable and Vout setup ? if not, could you please help explain the Tset clearly ?

Hi John,
Since I haven't received your reply for many days, I will close this item, if you have any questions, please feel free to contact me. Thanks !

Hi Kevin,

I have returned from being out of the office - the figure I noted is from the TPS2121 datasheet that defines tSET. It is the delay from the input to 10% of Vout.

tSET is defined in the bottom left:

Hi John,

I am sorry that we didn't define this parameter in the datasheet, it needs actual testing to get this parameter. But I don't have the EVM board in my hand, it may take a week to get the EVM, can you let the customer test it by themselves ?

Hi Kevin,

The customer doesn't have the EVM and isn't using the device on their board today. Testing on your side would be appreciated.

Hi John,
I will test it as soon as the EVM board arrives. Thanks !
Kevin
