In this post I have explained a simple way to enhance the the XL4015 DC to DC buck converter with an adjustable current limiter, which seems to be missing in the original module. About XL4015 The XL4015 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, specially designed for operating a 5 V, […]

Simple Adjustable Industrial Timer Circuit
In this post I have explained a simple and effective industrial timer circuit which can be universally used for most industrial and home timer based applications. The idea was requested by Mr. Vasilis K. Technical Specifications I have a question regarding the 4060 ic wired as “one shot timer.” If it can power on the […]
3 Solid-State Single IC 220V Adjustable Power Supply Circuits
These AC to DC power supplies use a single chip to convert mains 220 V or 120 V input AC into 12 V or 5 V DC without depending on a transformer. Three simple yet efficient 220V single chip based solid state transformerless adjustable solid-state power supply circuits are discussed here. The first one works […]
Adjustable 3V, 5V, 6V, 9V,12V,15V Dual Power Supply Circuit
The purpose of this paper is to detail a variable dual lab power supply circuit which has an adjustable range from 3V, 5V, 6V, 9V, 12V, and 15V or even more at an output current rate of 1 amp. Written By: Dhrubajyoti Biswas The Dual Power Supply Concept In regard to positive volt it is […]
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 […]
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 […]
