Hello everyone,I’m trying to locate the DSMPS 3kW – LLC STM32F334x firmware package, which is described as containing the following folders:Documentation – includes compressed HTML and LaTeX help files generated by DoxygenDrivers – includes HAL, LL, ...
3 Phase Delta and the EVALSTPM-3PHISO
I have the EVALSTPM-3PHISO. IT appears that it only measures Volts and amps on a single phase at a time, then switches to a different phase for 3 consecutive phases. We are working with Delta power (no neutral). Do the Sample and hold on the ADCs get...
Power Delivery possibilities
Hello, I am creating a board using the STUSB4500QTR and I saw something on a video that confused me. I want to use the IC to take in 100W (20V/5A) and output three different voltage rails: 3, 3.3 and 3.7. Each will have a fairly large curren...
