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 […]
FM Signal Booster Circuit with Adjustable Gain
Did you’ve ever had trouble catching or establishing connection with distant FM radio stations which were broadcasting programmes you wanted to listen to? Perhaps you’re aware there are a lot more faraway channels, further than the range of your FM receiver. Of course, you could purchase or construct a stronger FM tuner but, building a tunable FM […]
Modifying XL4015 Buck Converter with an Adjustable Current Limiter
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, […]
Adjustable Drill Machine Speed Controller Circuit
The proposed variable drill speed controller circuit maintains a constant (adjustable) speed over the drill machine motor, regardless of the load. One of the most used power tools is the power drill machine. Despite its innumerable advantages, the power drill has one major setback – constant high speed for many applications. Even when there are […]
