C Control of LED Brightness
Control LED brightness using Pulse Width Modulation (PWM) with a PWM signal applied to the external PWM input. The LED PWM
dimming occurs at the same frequency and duty cycle as the input signal. For all drivers, use PWM input frequency between 20Hz and
50kHz and duty cycle between 0% and 100%. Additionally, internal registers, accessed using the I2C compatible serial interface, allow
control of the PWM dimming frequency and duty cycle. For programming details see the “MSL3040/50/60/80/86/87/88 Programming
Guide”.
