LP8863-Q1: LED OUTPUT STRING (PWM FREQ RESULT)

Part Number: LP8863-Q1

Hi all

I have a question regarding the LP8863s LED Driver

currently I am verifying the LED Driver, we use the I2C register to set the LED Driver,

and for the LED Output String, we use 6 Channels with Automatic Phase Shift 60 degree,

and the dimming mode is PWM Mode

 

from the measurements. I got a PWM Frequency result of 2.46kHz (the same as the PWM Setting result of 11k Ohm = 2441Hz)

but I remember when we measured the LP8866S, TI said that when using a phase shift of 60 degrees, the PWM Frequency results would be 6x bigger,

So I want to confirm, is there really a difference between LP8866 and LP8863? Because the PWM Freq result in LP8863 is based n the setting "2441Hz" .  why on LP8863 the results are not 6x bigger?

 

Thank you

Best Regards
