The catch.. There's always a catch. I want this product to be able to run from 12V as well as 15,24,36,48V, etc.
Considered solutions. Run a buck/boost instead of a buck. Unfortunately that results in a switcher twice as big and 7 dollars instead of the above one which is only about 4 dollars.
Do you think something like the little network below the switcher with the two transistors will get the job done by essentially bypassing the switcher whenever the voltage is below 14V.
