Buck converters and remote sensing

BobTPH said:

What you showed was the output circuit of a buck converter. It lacks all the control circuitry.

It could be driven by a fixed PWM signal, and then it would be an unregulated buck converter. I.e. the output voltage would vary with the input voltage and load. If that is what you want, there is no sensing of the output, remote or not.

To make it a buck regulator, it needs a much more complex circuit as others have pointed out.
