Description
220Vac to 5Vdc Transformerless Power Supply Using LNK304
To design the schematic and PCB, I used Altium Designer 22 and the SamacSys component libraries (Altium plugin). To get high-quality fabricated PCB boards, I sent the Gerbers to PCBWay and purchased original components using the componentsearchengine.com. To test the current handling and stability of the output voltage, I used the Siglent SDL1020X-E DC Load and examined the power supply output noise using the Siglent SDS2102X Plus oscilloscope.
