Details
Each output port’s individual constant-current sink can
be set to be either half or full global current. The indi-
vidual currents are set by the output current registers
(Table

IOUT
Each output current can be set individually to best suit
the maximum operating current of an LED load, or even
adjusted on the fly to double the effective intensity con-
trol range of each output. When the global current reg-
ister is set to maximum, the individual current selection
is 10mA (half) or 20mA (full).
