MBI5024

Application Information

Constant Current

To design LED displays, MBI5024 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 ±2.5%, and that between ICs is less than ±3%.

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.
