Re: Can we PWM an LED backlight on LCD module
Well, that's disappointing. I looked only at Mouser, the IC alone is over $6 and most of the discrete components are not available. I don't know enough if I can replace them with components.Originally Posted by Ioannis

And the SMD designs had a LOT less power (my first choice, to have them fully assembled by JLCPCB). Microchip's app note dates from March 2001, gonna check out TI...
My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!

Re: Can we PWM an LED backlight on LCD module
Another idea would be to use a low drop linear regulator for 5 volt and use the cheap switch mode ones to lower the 24 volts down to 6-7 volts. That way power losses on the low drop would be minimal and still you will have good quality noise free 5v line.
