The circuit in question is probably as simple as it gets when it comes to a boost converter, and is not really a practical design. However it helps visualize what is going on, and exactly how a ...

Combining a buck-boost topology and Silent Switcher technology brings very low EMI at the highest power-conversion efficiency ...

ISSCC, the International Solid-state circuits conference ... Rather than having an external boost converter to produce enough volts, this design adds just two mosfets and an inductor to the Class-D ...
