Hi,

Let me talk about the operation of TPS25942A FLT pin in start up timing.
Customer wants to know the time when the FLT pin becomes OPEN after applying the input voltage.
Could you tell me this delay time?

Best Regards,

Hi Yusuke,

From the test results on EVM, there is a typical delay of around 70us from EN=HIGH to fltb=OPEN. Please let me know the significance of this parameter to the customer.

Best regards
Rakesh
