sam.moshiri Posted July 26, 2021 Report Share Posted July 26, 2021 DC to DC converters are quite popular among electronic enthusiasts and are widely used within the industry. There are three major types of non-isolated DC to DC converters: buck, boost, and buck-boost. In this article/video, I used there major components such as the famous UC3843 chip, a power Schottky diode, and an N-Channel Mosfet to design a compact DC to DC boost converter. The input voltage could be as low as 9V that makes it suitable for a variety of applications, such as 12V to 18V conversion to power a laptop computer using a single 12V battery. I used Altium Designer 21 and SamacSys component libraries to design the schematic and PCB. The PCBs have been fabricated by the PCBWay in the green solder mask. Also, I examined the noise figure of the circuit using the Siglent SDS2102X Plus/SDS1104X-E oscilloscope and Siglent SDM3045X multimeter. So let’s get started!
