Might be a simple question to some but is it ok to PWM their input or output?
I want to drive a few 10W LEDs and think of using converters to supply appropriate voltage for each color, but those on-board caps and advertised voltage reaction time make me think that it "will not blend"(c) with PWM..
How would you want to use PWM for the input ?
You can do that on the output. Perhaps with an extra capacitor, but those modules can handle switching loads very well.
The LM2596 has an on/off pin, which you can use for the PWM signal.
I know that has been done, you migh search www.hackaday.com for it.
The LM2596 has an "start up" circuit according to the datasheet. I don't know how fast that is. Perhaps you can find it in the datasheet.
Since those modules have a fixed frequency of 150kHz, a PWM signal of 100Hz for led's should be possible.
But you have to try it to be sure.
I'm sorry for archaeology.
Did someone made LM2596 voltage regulation via Arduino / ATmega?
I'm looking for step down buck converter with voltage regulation via Arduino.
kivig found other solution for his problem and didn't make this.
