Hi Peter,

Yes, the CTRL can be used directly to control LED current/brightness. But how much is the PWM frequency required?

If you want to find a LED driver that can be controlled on/off directly, recommend to take a look at the LP5524.

best regards,

Felix

Hi Sir,

I also suggested LP5524, but customer only needs 1 ch and PWM control function.

If LP5560 can be controlled by PWM via CTRL pin, that is great!
