Any cheap buck boards that takes 9V?

[Upplyst]

Hello!

Are there any cheap buck boards that takes 9V? I am planning on giving my old MAG 6D new life. I have a custom heatsink that fits the ssc seoul LED left over from previous modding. My aim is a black out/emergency light with looong runtime.


Be well/Henrik

Is this paragraph new? I don't remember seeing it before.

- Total input voltage must be 1-3V higher than output voltage, depending on the number of LED that you need. If you are running two LED, your battery voltage should ~2V higher than the LED total VF. If you are running one LED, your battery voltage should be ~1V higher than the LED VF.

I think it's saying the voltage must be at least 1-3 volts higher, since the Case 1 example given has a much higher input voltage.

These would also take up to 9v(but that might be pushing it, should be over 1 amp to the LED at that voltage)

The KD ones seems to be good.
