I need a simple synchronous buck converter capable of seamless CV/CC transition. V_IN_MAX=17V, I_OUT=3-5A (roughly), V_OUT=3V. I had googled a lot but was unable to find a nice part for the job. All the candidates either have too low I_OUT, self-protect themselves like Jackie Chan with various hiccup/latch off algorithms or require so many external components that it is hard to distinguish them from a discrete solution (the notorious LTC...). And the remaining few ones don't have legs, which excludes them from the BOM.
Do you know of something as simple as TPS54302 which would just start pumping current when overloaded? The limit value can be very rough; I don't care. Or do I really need to roll my own old-school truly hysteretic converter based on the INA293 or compatible and a bunch of comparators?
Best regards, Piotr
