Hi Keneth,

If we use the same LED circuit and use I2C from MCU to control brightness of RGB LED, we just onle need brightness

do you think LP5521 is a suitable solution? We need Linux driver support, and seems LP5521 have ready Linux to use.

or you have any other recommend part that can use I2C to control RGB brightness and also Linux driver support?

It seems LP5521 has more powerfull function that we don't need.

Thanks!

Sincerely,

Chin

LP5521 uses I2C to adjust the brightness and supports 25.5mA per channel.

If this is OK for you, LP5521 is a good fit.
