0 to 50 V Adjustable Switching Power Supply Circuit using IC LM2576
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 […]
22 Watt Stereo Amplifier Circuit using TDA1554
The IC TDA1554 based Amplifier circuit discussed in this article can provide up to 22 watts per channel into a couple of four-ohm loudspeakers. The main attraction is that you can construct it for less than $15. This implies that you may make a power amplifier for your car’s front speakers, another for the back […]

In this article we will explore 3 different Morse code practice oscillator circuits, for generating exact replication of Morse code signals in the form of dots and dashes. Contributed By: Anil Patil What is Morse Code Morse code is a legacy method of message encoding that uses rhythm and impulses to transmit telegraphic communication. Morse […]
How to Calculate Zener Diode Resistor
In this article I have explained how to calculate and the find the value of the zener diode resistor using simple formulas. What is a Zener Diode Zener diodes are semiconductor devices which are used for regulating an input DC voltage to any desired output voltage. The regulated output voltage value directly depends on the […]
Simple Buck Converter Circuits using Transistors
In this post I have explained some basic facts about DC to DC buck converters and also learn how to build a simple buck converter circuit. A buck converter is also popularly known as a step-down converter, since its basic function is to step down a higher input voltage level to a lower output voltage […]
