STEVAL-VP12201F

I don't know why ST don't include the transformer winding details into the STEVAL-VP12201F ??I even cannot find it on Wurth Elektronik site, these complications make it impossible for us to use it in our products.Is there any help from ST around here...

STEVAL-VP12201B

What is the possibility to feed the eSTEVAL-VP12201B from PFC with 385VDC?Do I still need to apply any filter at the DC input of the eSTEVAL-VP12201B when feeding it from PFC?In another word, I would like to feed it from a PFC with 385VDC without L1 ...

Supply management of powerstep01

I use powerstep01's datasheet "7.19 Supply management and internal voltage regulators".datasheet says: "VSREG must be always less than VBOOT". May be not Vboot, but Vbus?Also "The device can be protected from this event by adding an external low drop...

How to I determine the correct Resistor value for setting the current limit on the ST1PS02BQTR Buck Converter?

From looking at the datasheet for ST1PS02BQTR, I was able to determine what the default current limit, and that I just need to place a resistor there to set the current limit, but I didn't see any other documentation about what the relationship betwe...

STSPIN32F0 - Can I increase flash size?

I'm working with this MCU in a project and ran out of flash space. Would like to know if there is a wat to add an external flash to this or if there is bigger flash option.
