Does anyone know of a good reasonably efficient voltage step down regulator that can handle and input of at least 50v, and an output of around 48v?
Really stuck here - trying to make a flicker free dimmer for my monitor (which uses PWM dimming). The LEDs need 50v at full brightness, so what I was hoping to do was put a regulator between the monitor's own LED driver (at full brightness so no PWM) to take advantage of its current limiting, and just use the regulator to reduce the voltage when I need a lower brightness. Sure, max brightness will be slightly lower, but it's too bright anyway so I can take that trade.
I'm sure I can do it differently (using a CC step up regulator and a relay) but I'd just like to check before I look into that because this would be the easiest method.
