A good switching power supply requires a good printed circuit board. In order to make an efficient one, the PCB designer should understand the phenomenon behind the operation of the typical switching ...

This printed circuit board for the 5 VDC power supply was designed with EAGLE and fabricated onsite with the Othermill. Using the pictures, install and solder the following components in their ...

This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

When designing a mains power supply for a small load DC circuit, there are plenty of considerations. Small size, efficiency, and cost of materials all spring to mind. Potential lethality seems like it ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight, ...
