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 is circuit switching regulator 5V 5A for digital circuit.
Use IC LM2678-5.0 is High Efficiency 5V 5A Step-Down Voltage Regulator This is good power supply, small size and do not hot. Read more
