Other Parts Discussed in Thread: TLC5941
Hi Sir.,
my customer uses 10 TLC5941 to drive 160 LEDs for backlight. They use PWM mode with 6MHz GSCLK. below is the waveform. it looks correct for me.
They drive all LED in the same PWM setting.
Ch1: one of out pin
ch2: BLANK
CH3: GSCLK(it should be 6MHz. due to scope resolution, the frequency in scope is wrong.)
They can hear the audible noise.
Do you have any suggestion to reduce it?
BR,
frank
