Hi folks, I am in need of building a couple step-down voltage
regulator circuits to run some ardunio-like projects at 5VDC/3A for
prolonged periods of time from a 13.8VDC source.
I'm thinking the TI LM2678-5 5A VR IC might be a good choice for this
project. However, I am not an expert at all in VR design. Would
anyone have any other recommendations? I was going to start
experimenting with the circuit in the LM2678 data sheet.
I realize there are a bunch of similar, pre-built, 3A buck devices
like this flooding the Chinese ebay market. However, reviews are
mixed at best especially for prolonged use. I suspect this to be from
fake, copied, TI VR ICs and other sub-par components. I am not trying
to reinvent the wheel, I just need a reliable/clean way to provide 5V
@ 3A (max.) from 12-13.8VDC.
