I'm using a 5V buck regulator to power an LED (yes, I know I should be using a constant current LED driver).
I have resistors inline with the LEDs maintain 150mA per channel (RGBW).
The 5V buck regulator spikes to 7.5V for a fraction of a second when turning it on and it ends up burning out one channel of the RGBW LED.
I think I should be adding inductors inline with each channel to prevent that sharp change in current from burning out the the LED.
How do you size an inductor to prevent that brief increase in current?
