I wanted to get together a simple and efficient 12V to 5V switching power regulator using only through-hole components that can be soldered to a nice protoboard. For my purposes, I need to provide 0.25A - 0.5A. Maybe 0.75A max but I doubt it. I started with the LM2675. Without making one before and only having the datasheet and google, I wanted to know if I selected proper components before I pull trigger. I will follow the manufacturers typical application schematic.
L1: 2100HT-680-V-RC - 68uH, 5.1A, 44 mOhm DCR, 5.1 Idc
Cout: RR71C680MDN1 - 68uF, 16V, 7mOhm ESR
Cin: ESY107M025AE3AA - 100uF, 25V, 130mOhm ESR
I've read a lot of recommendations to use ceramic caps for their low ESR but almost always find aluminum electrolytic caps used elsewhere. Cout was chosen for its very low ESR, but is the ESR value of Cout low enough? Are there other specifications of the capacitors I am not considering? Correct me if I'm wrong but I think the inductor should be more than good for my use. Any input would be greatly appreciated!
