Hi Sir,
How many bits of the PWM input does LP8869 chip support?
I also wanna confirm which of the every outputs out1-out3 corresponds to the high 8 bit or the low 8 bit.
My application is the industrial control board outputs one channel 24bit PWM signal,
After processing by TI chip, output three channels signal to drive RGB three color lamp,
to achieve different color control, the total current of three lamps shall not exceed 100mA and the system voltage shall be 5V.
RGB mixing wanna to reach different colors,
the color modification only needs the client master to modify the corresponding PWM duty cycle.
In order to save the development cycle, the IC device needs to work in analog mode rather than digital mode,
that is, this IC is not programmed separately.
In short, the input PWM signal is processed to drive RGB to achieve mixed dimming in 5V power supply mode.
The PWM input supports 24 bit input.
I wanna confirm if LP8869 is suitable or not.
if not, can you recommend a suitable TI device for my application?
Thanks.
