Web11 feb. 2024 · For smooth dimming, you need 12-bit PWM minimum. Can’t use a high frequency for dimming either. The mosfet switch frequency is “PWM frequency * bit depth”. 62.5kHz*256= 16Mhz in your case. Drop PWM to <1kHz (I use 12-bit/200Hz). Don’t use a DAC/mosfet with a 100watt LED. That would use the mosfet in it’s linear region. WebThe constant current circuit can have noise filtering, yet still be switched at speed.

WebSo first I suggest you to make a roughly 5kHz pwm signal and apply it to your LEDs. If you want to use a LowPass the calculation is easy: f=1/ (2*pi sqrt (C L)) This describes the -3dB frequency. So if you apply any signal, frequencies above f will be attenuated by 3dB at f, and falling with 40dB/decade.
