Team,
I have seen the below E2E post about "constant current":
https://e2e.ti.com/support/power_management/led_driver/f/192/p/149979/542323#542323
Q:Could you please confirm that "constant current" really means that the current on given output (OUTn pins) will be kept constant for a given step?
The datasheet is not very clear. "constant current" seems to be related to the current difference between different outputs:
http://www.ti.com/product/TLC59108/datasheet/application_and_implementation?search=constant,current#SLDS1562956
Q:Is it true as well for the TLC59108F that has open-drain outputs?
Q: Or will the 97kHz PWM will be seen directly on the outputs (OUTn)?
If this is the case this will likely create ripple and could potentially to lead to EMI problems? Any advise to overcome this?
Thanks in advance,
Anthony
