  • Yep, I see where my thinking was wrong. I was not considering the voltage side of things and the minor differences there, just the current side. So when the buck starts its cycle, it ramps the voltage until it gets a closed circuit then feeds/allows a 350mA draw down the line?

  • But let's say you remove the current limiting resistors from the equation. In practice would the current divide equally across several paralleled sections of LEDs in series... If you do the math on the number of sections needed to adequately sink the source current...

  • So, instead of one big beefy LED let's say I wanted to run a number of smaller LEDs off the buck in place of series resistors to save on heat and efficiency. If I have 3v LEDs and want to drive them close to 30mA, by my math if I have them in sections of three in series I can parallel link 12 sections together with a current draw of around 29mA per section with a 12v power source. Is there an issue with the buck having to sink the remaining 3~3.5v?

No public wish lists :(
