Note that a driver will take the lowest of all LED limits
|
||
|
|
since the chip has a single global setting. The lowest value
|
||
|
|
will be chosen due to the PWM specificity, where lower
|
||
|
|
brightness is achieved by reducing the duty-cycle of pulses
|
||
|
|
and not the current, which will always have its peak value
|
||
|
|
equal to led-max-microamp.
