DC Boost Converter circuit 3-4V to 12V-13.8V
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.

You want to use a DC regulator or learn about voltage regulators using 2N3055. Why use this transistor? Normally, it can be used with loads that require a current not exceeding 2A and a voltage of not more than 30V. This is enough for general work. It’s a transistor that people like to use for … Read more
