3V to 12V DC Boost Converter Circuit
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
Although the input voltage change between 5V and 13V but the output voltage is steady at 12V Read more
Here is 3.7V to 5V boost converter or step up switching circuit using MC34063 and a few parts,1N5819,100uH. For 200mA-300mA of load current. Read more
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
