Feed error on the STEVAL-CTM009V1 board

The supply of the STEVAL-CTM009V1 board is shown to be up to 48 V. However, the A7986ATR writes that the A6902D13TR buck converter has a maximum supply of 38V.How does this board work at 48V?Or is the feeding range of the board written wrong?

ABOUT THE SODERABILITY OF TIP147

Can this item withstand 227C work through Wave soldering / soldering production ?or any document support? thanks.

Change the internal resistance of "2STBN15D100"

The internal resistance of "2STBN15D100" is described in the datasheet as shown below.By the way, if you actually measure the resistance between Base(1) and Emitter(3), it will measure around 12K ohm.I think that the data sheet will measure around 8K...

Need powerstep01 sample circuit for reference.

sample circuit need

For a new application,we need an AEC Qualified part with the specifications same as VIPER16LN.Is there any AEC Qualified Buck convertor with the same spec as VIPER16LN is applicable with ST?

Hi, for the STM32F446 series timers in encoder mode, which interrupt flag is set when an encoder phase state error is detected? In a presentation of the STM32G4-GPTIM it is mentioned that this feature exists, but in the f446 refman I cannot find it. Thx!

Is STUSB4700QTR power delivery IC compatible to be integrated with LLC Topology ?

I have to implement a power delivery system, for which I came across the power delivery IC ( STUSB4700QTR ) . But looking at the reference designs given in the Datasheets it can be seen that it has been implemented with the Buck and Flyback topology....

Is it possibile to power the board B-G431B-ESC1 with a 2s battery pack? I look the schematic and there is not an electronic limitation (all the components and uP are powered with +5 or +3.3) , so I wnat to know, why there is this limitation.

It appeared that nobody answer on spv1050 questions.. I had same problem as ask before : could not activate ldo if there are no charge ! even if battery is full! This is crazy! Also boost buck not working as expected.

Well, I have a lipoly single cell and ixolar solar cell from iXys (Vmpp = 4.3v) connect to the spv1050.Buck boost not working correctly, efficiently is worst bad. (I got onlt a fraction of Amp from a direct connection to my battery!)it is impossible ...
