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.

Figure 6.1: Simplified Boost Converter Circuit Boost converters have some disadvantages, especially when used as LED drivers, due to the low dynamic impedance of the LED string. The output current of ...

The discontinuous conduction mode is described and analyzed. A number of well-known converter circuit topologies are explored, including those with transformer isolation. The homework assignments ...
