SINGLE BATTERY BRIGHT WHITE LED BURNER DC-DC CONVERTER SCHEMATIC CIRCUIT DIAGRAM

With a single battery, the LED lights have been around for quite a while. I thought we would find a suitable circuit and use a few candles instead of candles.

I even designed the pcb as a smd so that I can take up a little space and face the SMD thing. It was very difficult to work because the eyes were not like the old ones. If I did not use a magnifying glass during installation, I could not finish it. I also fixed the tape with adhesive tape on both sides while the pcb was soldering. Otherwise he could not be fixed and was constantly moving.

Blocking Oscillator is defined as a circuit that works. The coil in charge is cheap and the resistance type is chosen so that it takes up little space, but after about 10 seconds the led is out.

Then the current passing through the coil was measured and it was observed that 300mA was passed. Unfortunately, the resistance type bobbins did not fit in this and the coil wire that they were wrapped around was quite thin. The 100uH coil that I removed from the ATX power supplies (presumably -12V channel) worked fine.
