DLPA3005: Change 16A to 12A of the max current of LED

Part Number: DLPA3005

Tool/software:

Hello TI,

Regarding DLPA3005, default configuration of max current is 16A. If we'd like to set the current = Max12A, should we change just RLIM(=12.5mΩ) value? Should we change other factors?(Such as parameters of the DLPC3429 firmware.)

Regards,

Hello User,

Can you please provide what the controller is using with DLPA3005? DLPC3429 sounds like not correct.

Why do you want to change the default max RGB current to 12A? Is this for safety use case in your design?

Regards,

Lori
