[Lutz] needed a converter that could boost 5 V to 30 V to power a string of LEDs. The solution was to use low cost ATtiny85 and some passive components to implement a boost converter. This circuit ...

Over at SpriteMods, [sprite_tm] realized that a microcontroller could be used as a boost converter to power itself. A boost converter steps up voltage from a battery by switching the output of a coil.

One example would be if an input voltage range ... video series about power and analog tips. A switch-mode buck-boost converter works with a certain switching frequency and generates pulsed ...
