Search for power supply chip

probably because my c:\blah\\rusefi_kneelo\hardware\rusefi_lib is an empty folder. I'm not sure how the symbol is found on your system.

If that's empty, you're missing the submodule for libs,

Code: Select all

git submodule update --init

It would appear you found a different datasheet than I have found. I found this 240 page beauty. However it does not have a section 16.
https://media.digikey.com/pdf/Data%20Sheets/Infineon%20PDFs/TLF35584_Rev2.0_3-16-17.pdf

Can you post a link to the datasheet you are using as a reference.

Per the below thread, the TLF35584 can be set to no use SPI.

In case you don't want to use watchdogs and error monitoring, you can connect MPS/TM pin to high always so that watchdogs and error monitoring are disabled. The device stays in INIT state providing all the output voltages.

So good news, we can make it work, then deal with SPI at a later date.

For the TortiseGit crowd, that's right click on the top level repo folder --> TortiseGit --> sub-module Update

So secret tip. If you don't find section 16 in the table of contents, go look for it any how. You'll find it's a secret section which is not advertised in the TOC.

I found page 233 of this 240 page document https://media.digikey.com/pdf/Data%20Sheets/Infineon%20PDFs/TLF35584_Rev2.0_3-16-17.pdf . It has a section titled.

16 Application Information

Unfortunately, it does not detail how they derived the 22uH value. As well it appears they don't have these values on there eval boards. So I still look for details on how to select the inductor's and capacitor's.

How about TLE8888-1QK? It seems to include a bit more than just power supply. Available on Mouser in singles for $17.

I find this to be a lot better option.

I have this on order already to try out.
