Hello,
We are using one TLC6896 to drive a 48x16 monocolor red led matrix. In our schematic we use 6.8k for Rref. We want to achieve 20 mA output current. I am attaching our list of parameters that we are currently using. The problem we encountered is that the costumer wants a higher intensity. Are the below settings for the register correct to get 20mA per channel?
