In this article I will try to explain the construction of a 1.23 V to 50 V adjustable switching power supply circuit using the IC LM2576. The LM2576 family of regulators is a monolithic integrated circuit that performs all of the active operations of a step-down (buck) switching regulator. It offers exceptional line and load […]

Adjustable Timer Circuit Using IC 555
IC 555 adjustable timer explained here can be adjusted from any time delay 1 second to 3 hours for operating any load through a relay control The produced time delay is fully adjustable and the user has the freedom to set the time period as desired. There are many ways of making simple timer circuits […]
How to Make Adjustable Current Limiter Circuits
In many sensitive electronic circuits or loads, adjusting the current limit in its power supply could be one of the most crucial requirements for ensuring a fail proof safety for the various vulnerable devices. A simple method of sensing current this using resistors has been discussed in this article. Integrating a Current Sensor Stage The […]
Making an Adjustable Electromagnet Circuit
This article describes a simple circuit which can be used for pulsing an electromagnet. The IC 555 once again becomes the central part of the circuit. I have explained the making procedure of this simple adjustable electromagnet circuit for varying the magnetic power of an electromagnet. Introduction The circuit was requested by Mr.Jason, one of […]
