DC to DC buck converter is a famous topology in the electronic and a widely used circuit in electronic devices. A buck converter steps down the input voltage while it increases the output current. In this article/video, I have discussed a DC to DC buck converter that can be used effectively as a switching power supply. The output voltage and current are adjustable: 1.25V to 30V and 10mA to 6A (continuous). The power supply supports the constant voltage (CV) and constant current (CC) features. Two LEDs demonstrate the CV and CC status. The circuit is compact and both sides of the PCB have been used to mount the components.

To design the schematic and PCB, I used Altium Designer 21, also the SamacSys component libraries (Altium plugin) to install the missing schematic symbols/PCB footprints. To get high-quality fabricated PCB boards, I sent the Gerbers to PCBWay.

To test the circuit, I used the power analysis feature of the Siglent SDS2102X Plus oscilloscope (or SDS1104X-E), Siglent SDL1020X-E DC Load, and Siglent SDM3045X multimeter. Isn’t cool, 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?
