Part Number: TPS54425 Tool/software: Hello,
My customer is using TPS54425 as shown below.
- VIN = 12V
There is a difference in input current between the development board and the mass-produced board even though the output load is the same at 5 V.
Q1…
Part Number: TPS54425 Tool/software: Thank you for your help..
I am using it with 12V input and 5V output.
If the input power is cut off for about 150ms, the output stops. I think this is due to the UVP function, but please let me know the cause and…
