But i think in the quantity i need for the project, i can make my own for a better price.
The big problem is stability, unless the PCB is "right" they will go unstable at certain currents. This gets more critical as the current increases.
were you making the converter with an IC like lm2596
I am powering ws2812b leds so I don't think a constant current driver will be suitable.
datasheet for the chip i'm considering using, it has a nice drawing for 75w...
I am powering ws2812b leds
i have got 12v strips
Why can't i replicate it? It's very detailed even down the the component choice. Only they they didn't specifically list is the model inductor but they did give a value, and elsewhere in the datasheet it has some detailed information about picking inductors...
