The objective of this project is to convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time.

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 ...

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 ...

Op-amps require dual-polarity supply for proper operation. When working with battery supply, it becomes difficult to get dual power supply for the op-amps. Presented here is a simple circuit that ...

This circuit is a very simple voltage monitoring device for +5V VCC supply lines. It can be used to monitor the power supply of a microcontroller (uC) by indicating when the supply level raises above ...

Abstract: This article presents the design and experiment of a multi-output DC supply for a 5G millimeter-wave front-end module, with some specified requirements, such as miniaturization of power ...
