I will be more specific. It concerns the following schematic. I want to know, at least approximately, if the peak current flowing through C6 and the UCC373 chips. Because, for convenience reasons, I am using a single UCC27425 that has both non-inverting and inverting on the once chip. However these have a maximum current rating of 4.5A rather than 9A.
It has been rather surprising to me how bloody hard I have found it to find any SPECIFICS on this sort of thing, while searching the net. And even the answers in here don't seem to give me any SPECIFICS that will enable me to gain a decent understanding of how to perform this sort of calculation.
One detailed worked example with this specific schematic, with some explanations about each step in the calculation would be GREATLY appreciated and will set me up for all similar circuits in the future. Assuming that the supply voltage is 12V (as per the spec) and the duty cycle of U5 is 90%.
My problem is that I am not formally trained in electronics and there are significant gaps in my knowledge. So just a general description of how to do the calculation, as in here so far, is not enough.
The author of this schematic must have done some calculations to find the right variety of gate driver to use, as opposed to just trying different chips until he found one that didn't blow up.
