You’ve got to be kidding. An arduino as a controller for a boost converted? Just use a dedicated IC, they are cheap and reliable. I honestly do not see the hack value of this project.

Well there can be some more special applications where a µC-based controlling of a Buck/Boost converter can actually be useful: 1. Include battery charging logic (used e.g. in the Imax B6 charger) 2.

On board the chip, called MAX77654, is a single-inductor triple-output buck-boost regulator that can provide outputs from 0.8V to 5.5V, two 100mA LDOs, a Li-ion-Li-poly charger, three GPIOs and a ...
