PCA9745B PWM freq.

hyjung — Wed, 03 Apr 2024 05:21:26 GMT

Hi all.

Is PCA9745B capable of PWM freq. of 200Hz on individual channels?

It seems impossible because it has a fixed freq.

If so, please let me know if there is an IC that supports SPI communication over 12 channels and can

control individual channels at 200Hz.

Thank you.

Do you want to drive a motor instead of LED?

Hi.

no. I'm looking for an LED driver.

Thank you.
