Hello there!
I'm lookong forward to build a 25A+ synchronous buck converter and I already have all the theory behind it learned. My problem is that I want high switchnig frequency (at least 500kHz) and I can not find reasonably proced control ICs for this application.
I've spent like 6 hours looking for some IC that I can buy from aliexpress (or anywhere under 5$/piece)
Is there any Arduino compatible MCU that can supply PWM such high frequency and a reasonable resolution? I know about the STM32 but it's just too overkill for this application.
Or is there any "cheap" IC that could fulfill this task?
