In this instructable we will make a portable, variable power supply, using a step down buck converter, three 18650 cells, and a 7-segment display voltage readout. 2 - 12 volts, though the led readout cannot read below 2. I needed an output voltage between 0 and 12V, current limit between 10mA and 1A, and load regulation 0. Discover how. . So here what we done is, we built one very easy and simple transformerless power supply circuit using just few parts and we used MOSFET as the main control device. Let's start with the needed supplies. It is used to provide a stable and adjustable voltage to various electronic devices.
