there are a few off-line buck voltage regs around, Pic related is almost as simple as any other buck and is available from some ali sellers
if you want an adjustable current regulator, the AL9902 is interesting and easy to use, works up to 1A, although the reference voltage isn't adjustable so you have to adjust the shunt instead. also, not available on ali as far as I can tell, and Digi-Key is closing them out
