Can the ST1PS01EJR programmable Switching Regulator change voltage levels on an active MCU?

The use case is a L4xx MCU that needs to write to an SD card, most of the time the MCU sleeps and checks sensors. The ST1PS01EJR can be configured to start up at 1.8V and then the MCU could change the output to 3.3V write the data then change back to...

Buck-boost, 3v to 6.4v in, white LED drive out, 3A, how to handle the high end of Vin with a buck-boost

I need to run a while LED (output voltage range from 2.5-4.5v 4A surge, 3A steady state) from a battery source that can range from 3v to 6.4v in. So it's a buck-boost. I haven't been able to find a buck-boost that has a Vin higher than 5, with an abs...

I believe there is an error in AN5114 Section 3.3.1 where R1+R2 is calculated: seems like the V_photo term was disregarded. Was there then higher ripple measured across the TRIAC than was expected?

Hello, dear colleagues! I didn't find any references to the marking and datecode of the LD1117S12CTR component in the documentation.

The first question is: does the LD12 label correspond to the LD1117S12CTR part number? The second question F928 is a datacode? If so, what date is indicated here?
