PRODUCTION DATA.
The maximum output LED current is set by an external resistor value. The LEDx_CURRENT[11:0] registers can also be used to individually adjust each string’s current down from this maximum. The default value for all the LEDx_CURRENT[11:0] registers is the maximum (4095). Equation 11 is used to calculate the current setting of an individual string:
The LEDx_CURRENT[11:0] registers updates are also latched by the LOAD_BRT_DB register similar to the individual brightness registers. This is done so all LED currents can be updated simultaneously. The default value for all the LEDx_CURRENT[11:0] registers is FFFh.
