It is a 1.5V Step down Switching regulator using KA34063/MC34063. Imagine you have an old MP3 player it needs a 1.5V battery. But you only have the power bank, USB port 5V output. Sure, it doesn’t work. Therefore, this circuit is a good solution. Read more
Switching power supplies are everywhere—from phone chargers to LED drivers. This guide introduces the core ideas behind switching circuits, including buck, boost, and other DC-to-DC converters. Meet a Switching Power Supply? Switching power supplies convert electrical energy efficiently by turning the input voltage on and off rapidly. Unlike linear regulators, they waste very little energy … Read more
An inductor is one of the common electronic components alongside a capacitor and a resistor. Let’s understand how it works and how to use it. Read more
I like the 12V LED. But I have only 3V of batteries. So, No light. When using this circuit, I can get light of the LED at 100 mA. And, an adjustable output voltage.
Here are 4 examples of a buck converter circuit or step-down converter. There are many ways to make it, such as using transistors or ICs. Read more
