Versatile And Open Source LiPo bBattery Breadboard Power Supply

Orlando Hoilett from Calvary Engineering LLC designed a  versatile Li-Po battery breadboard power supply and wrote an Instructables on it. This power supply outputs 3.3V to the breadboard and takes input from a single-cell LiPo battery. The breadboard power supply also has the ability to charge the battery without needing to separate it from the circuit board. More importantly, this …

TORPEDO: an all-purpose switched-mode power supply

Having explained the theory, let’s see in practice the project of the SEPIC power supply. In this post we discussed – on a theoretical level (even if in a simplified way) – the SEPIC switching converters, also highlighting advantages and disadvantages, and giving you the basics for the calculation of their components. Let’s get to …
