DC to DC Boost Converter using UC3843

Post by sam.mo » Mon Jul 26, 2021 4:48 pm

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!

Thank you for sharing.
What examples of typical use case do you see for this in conjunction with a Red Pitaya unit?
