How does TLC5955 change It's current setting (MC/DC/BC) as TLC5955 is running ?
Our customer want to change Maximun current for local dimming usage...

IF TLC5955 does, could you tell us a flowchat or process to set TLC5955(TL6C5478)?

IF TLC5955 doesn't , Should we set MC to the 31.0mA at initial phase?

Thanks.

Hi Jacky,

Since TLC5955 is a 4-wire serial interface, so my understanding is that we can support to control MC/DC/BC by interface. So do you mean how to use interface to control MC/DC/BC bit?

No, I didn't mean the hardware control,because we did drive (initiate )TLC5955 successfully
I want to check whether if TLC5955 can change it's (MC) maxcurrent with a safety percedure as TLC5955 is running and output current.

Hi Jacky,

I think it's no problem if you want to change the MC max current when TLC5955 is running.
