Feature                        

Compatible with MBI5168 in package and electrical characteristics
Exploit Share-I-O? technique to provide two operation modes:
Normal Mode with the same functionality as MB5168, Current Adjust Mode to program output current gain
8 constant-current output channels
Output current adjusted through an external resistor
Constant output current range: 5 -120 mA
Excellent output current accuracy, between channels: < ±3% (max.), and
between ICs: < ±6% (max.)
Constant output current invariant to load voltage change
Fast response of output current,
(min.): 200 ns @Iout < 60mA
(min.): 400 ns @Iout = 60~100mA
25MHz clock frequency
Schmitt trigger input
3.3V/5V supply voltage
256-step run-time programmable output current gain suitable for white balance application
Optional for “Pb-free & Green” Package
Applications
﹡Message Signs
﹡Outdoor LED Video Displays
﹡Indoor LED Video Displays
