Adjustable 1.2V to100V DC Buck Converter Circuit using LM5164

Last Updated on April 25, 2025 by Swagatam Leave a Comment

Ok now we have this LM5164 chip, and we want to drop voltage from 100V down to let’s say 12V, right? But we also need 1A output so we need to design everything properly. Now this chip is cool because it has ultra-low quiescent current (IQ) so it does not waste much power when it […]

Step-Down Adjustable Voltage, Current Regulator Circuit using LM2673

Last Updated on February 7, 2025 by Swagatam Leave a Comment

The LM2673 series of regulators is a collection of monolithic integrated circuits that are designed to provide all the active functions needed for making a step-down, or buck converter, switching regulator circuit. This means that they are capable of driving loads of up to 3 amps while maintaining excellent line and load regulation characteristics. One […]

Adjustable Voltage Regulator Circuit using LM324 IC with Over Current Protection

Last Updated on February 17, 2024 by Swagatam 4 Comments

LM324 voltage regulator circuit

In this post I have explained how a single LM324 IC can be used to create an adjustable voltage regulator circuit with overload and over current protections. Basic Working A basic IC LM324 quad operational amplifier regulates an unregulated 28-volt input source to approximately ±0.02%, resulting in a 1 amp 0 to -20 V supply. The […]

FM Signal Booster Circuit with Adjustable Gain

Last Updated on January 11, 2023 by Swagatam 12 Comments

V shape antenna

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 […]
