Part Number: TPS54040A For this part, the leads of the parts were found as discoloration, seems like oxidation as attached photo.
We saw that lead finish is copper, is that normal? And is that still good to use?
Thanks,
Brian
Part Number: TPS54040A Other Parts Discussed in Thread: LM46000 , LM46001 Hi,
I am considering using TPS54040A device. In using, there is one concern, so I would like to ask a question. In my specification, I assume input of 40V at the maximum. As far…
Part Number: TPS54040ATPS54040A Enable threshold voltage is Min:1.11V Typ:1.25V Max:1.36V (@TJ = –40°C to 150°C, VIN = 3.5 to 42V)
Please let us know Enable threshold voltage (@–25°C to 85°C)

I'm currently looking at using the TPS54040A for a Buck-Boost application with the following parameters:
Vin: 13 - 17V
Vout: 15V +/- 5%
Vripple…
I do not think the Efuse is the limitation. I think you just have to select R7, R11 and R10 as shown in Eq 24 and 25. to change the output voltage range.
Other Parts Discussed in Thread: TPS54040A Hi,
which is the constructive technology (CMOS/BicMOS.....) of TPS54040A IC?
I need it for MTBF calculation and information it isn't declared in the datasheet.
Best regards

Hi,
Currently, we're using the TPS54040A on a downhole device and supplies around 100mA. With this current rating, can TPS54040A function without failure after 3-6 months of continuous operation?
