TPS24710/11/12/13 Hot-Swap Controller Circuit Explained

Last Updated on February 14, 2025 by Swagatam Leave a Comment

When we talk about hot-swap controllers, it is basically an electronic device or integrated circuit (IC) that allows you to the insert or/and remove circuit boards, modules or parts within an active system without having you to switch off the system. It regulates the surge current whenever a component is installed and protects from short […]

Simple Boost Converter Circuit Diagrams using Transistors

Last Updated on January 27, 2025 by Swagatam Leave a Comment

boost converter working model

In this post I have explained a few very simple boost converter circuits using only BJTs, or transistors. Let’s learn more. What is a Boost Converter A DC boost converter circuit is designed for stepping-up or boosting a small input voltage levels to a desired higher output voltage level, hence the name “boost” converter. Since […]

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 […]
