Description

My design uses two separate LM2576 switching regulators that power the output through diodes to isolate them. I also have an extra output filter to minimize ripple and voltage spikes. My goal with this project was to create something that is more heavy-duty and reliable than most cheap BEC modules for RC models you can buy.
