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 Class B testing without any filters on the input.
