I have known that the LM317 as a current limiting regulator gets damn hot!!!
so there is alot of waste energy
how do I minimize that?
I now want to use the LM317 to get a precise voltage. of 19.2v
can you help me know more about what waste energy would be if my device used 17v @ 300ma
would the lm317 get hot?
the input voltage to the LM317 would be from 21v-28v
The main Idea is, The special High tech PSU for LED lights has input volts from 7v-24v
I am scared to over power this module, dont want to pump 26-28v into it
so I want to drive 4x LEDs @ 300ma requires 17volt this psu if upto 78% efficient AND MY amp meter shows high then that! the efficiency is great
EDIT: Or is it possible to CLAMP a voltage at the input of my MAIN device.....?
I dont want more then 24v to go in... because of solar the voltage dips and raise
