MBI5026
16-bit Constant Current LED Sink Driver
Application Information
Constant Current
To design LED displays, MBI5026 provides nearly no variations in current from channel to
channel and from IC to IC. This can be achieved by:
1) The maximum current variation between channels is less than ±3%, and that between ICs is
less than ±6%.
2) In addition, the current characteristic of output stage is flat and users can refer to the figure
as shown below. The output current can be kept constant regardless of the variations of LED
forward voltages (Vf). This performs as a perfection of load regulation.
