Hi all,

In comparator section of reference manual of stm32f30x devices. It is mentioned:

''Cycle-by-cycle current control loop when combined with the DAC and a PWM output

from a timer''.

What does it mean? Is there some explanations on the web?

Surely you are right.

I just wanted to point out another usage of the DAC in control loops.

In commercial LED converters, there are usually no potentiometer. Instead, dimming by remote command (usually DALI) is a requirement.

And yes, it adds costs to the MCU.

But that is a rather specific topic ...
