The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.
