In most of the power supply circuit designs, after the rectification stage of the AC signal, large, heavy and expensive electrolytic capacitors are used to avoid the ripple voltage at the output. In ...

Even though the cables between a source supply and a regulator are basic dc, some basic issues must be addressed to ensure viable results and test integrity. Every engineer knows that a stable, ...

Useful for electronics hobbyists, this linear workbench desktop power supply circuit converts a high input voltage (12V) from the SMPS of a PC into low output voltage (1.25 to 9 volts). An adjustable ...

Linear regulators have limitations with regard to supplying a quiet voltage rail. Alternatively, some very quiet switch-mode power converters, along with some design considerations, can provide a very ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...

Electronic enthusiasts looking for a way to control power to the next project from a 9 V battery may be interested in a small device called snapVCC. Available to purchase from the Crowd Supply website ...
