I'm trying to determine a standard PWM frequency output for RGBW controllers.
I see a lot of constant current LED chips call out a maximum PWM frequency input between 300 and 500 Hz.
1. I assume this indicates that 300 to 500 Hz is standard?
I've seen a 12 Vdc 385 Hz RGBW controller pass FCC...
Questions:
1. Why do switching regulator ICs have dedicated PWM inputs pins?
2. Can you use PWM on a low side switch at the output of a constant voltage buck regulator module? For instance Remcom Power's R-78E5.0-1.0. My concern is that dedicated PWM inputs operate differently than using an...
