A few years ago, I wrote about the powerful DC motor driver based on IR2110. This construction appeared to be quite popular. This time I want to describe a much compact and simpler (but still very powerful) solution with IRS2104. This device can be used to control any power-hungry DC load like DC motors, heaters, and so on.
This is the second part of the Allsky cycle, and I want to describe powering and protection of this device. Please read the first part to get basic information about this project.
