Soon later, I will also perform the step-response test and demonstrate the results.ĭownload the Gerber or order 10Pcs high-quality boards, for just 5 USD To get high-quality fabricated boards, I sent the Gerber files to PCBWay and tested the circuit for output stability and noise, using a DC load, A multimeter, and an oscilloscope. The fast component search engine (Octopart) allowed me to quickly consider components’ information and also generate the BOM. To design the schematic and PCB, I used Altium Designer 23 and shared the project with my friends using Altium-365. I have followed several PCB design rules to ensure low noise, low EMI, and high stability of the output voltage.
It’s a high-frequency and efficient buck converter chip that provides tight voltage regulation. In this article/video, I introduce an adjustable 5A DC-to-DC converter circuit that uses an advanced chip, made by Texas Instruments, which is TPS5450. Sometimes a buck converter is also called a step-down converter and a boost converter is also called a step-up converter. There are three major types of DC-to-DC converters (non-isolated): Buck, Boost, and Buck-Boost.
