Resolved! STSW-DABBIDIR , where is the code.
Imagine my susprise when i discovered ST actually offers a DAB "software" for their 25KW evaluation board using stm32G474RE. And i go to ST's website.And the only downloadables are binary files and a lazy one page .pdf Am i missign something here? wh...
Transformer saturation current calculation when using STCH03
I believe the VCX comparator is designed to clamp the maximum primary current, but there is no equation in Figure 7 of the datasheet to describe the relationship between IFF, RFF, and line voltage. Without an equation for IFF, it is difficult to size...
