Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

System boards today have an increasing number of power rails and supplies. Since solution size, efficiency, thermal and transient performance are all critical for advanced power solutions, it is more ...

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices. Their ...

Learn how to select a power-supply configuration based on PPG system requirements. Review the implementation of switched-mode power-supply reference circuits for both discrete (part one) and ...

Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design ...
