I am designing a 36V ebike battery charger that can be powered from an off-grid
48VDC solar array. I have a Spice simulation of the buck converter stage
working. It's conceptually simple, but the devil's in the details and I am
looking for advice on component selection. I was looking for parts available
through Digikey. So far, I plan to use a FAN7190 high-side driver and a BUK9230
NMOS FET for the converter switch and a second BUK9230 coupled with an LTC4357
ideal diode controller for the flyback diode.
I can send more info on the design (schematics, Spice simulation, etc.) if you
are interested.
Thanks,
Scott
