I'm working on a project where non-trivial currents (theoretical peak ~6A) are needed at several different voltages. Since this is battery-powered, I initially started looking at finding an appropriate switching voltage regulator. After looking into a couple different ICs, I found that the prices (including all of the additional components) were coming out around $15 to $20.
I then stumbled on BECs, which are widely used in the R/C market and seem to effectively be pre-packaged voltage regulators (i.e. including all of the additional components). Here's an example.
Although I'm not clear on what the name means (it stands for "battery elimination circuit"), it seems that a BEC would serve my purposes at a slightly lower cost and with a lot less work than creating the circuitry from scratch.
Is there any reason why a BEC wouldn't be a viable option for voltage regulation in a non-R/C application?
