A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a ...

The ICL7660 and ICL7660A are monolithic CMOS charge pump voltage converters that converts the input voltage ranges of +1.5V to +10.0V to the output voltage ranges of -1.5V to -10.0V. The ICL7660 and ...

Using this versatile power supply circuit, you can obtain the following voltages (approx.) at a current limited to one ampere: 3.3V, 5V, 6V, 9V, 12V and 15V. The AC mains is stepped down by ...

This project is an electronic power supply circuit that can be powered by either 12V (AC or DC) or 220V AC, and outputs regulated 5V or 3.3V DC. It includes input protection, voltage regulation, and ...

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 ...

This mini ups circuit provides an uninterrupted power supply (UPS) to operate 12V, 9V and 5V DC-powered instruments at up to 1A current. The backup battery takes up the load without spikes or delay ...

The aim: Create a 3.3V source from a –5V supply. You can obtain a precise, positive-output voltage from a negative-voltage supply with a boost converter and a linear regulator. The input and output ...
