4.5V~5.7V
6.5V
0 ~ 70°C
RED：60mA(Adjustment external resister:20m~60mA)
GREEN: (Programmable: RED-29% ; 4.17% step )
BLUE： (Programmable: RED-29% ; 4.17% step )
Usable Vf range of the LED is from 1.5V to <LVDD-0.5V>.
The resistance for the current regulation is usable in
1/16W -type. The number of channels of applying an
current to the LED is at the same time to one or two.
When the external resistance value becomes the
assumption outside, it has the protection circuit which
doesn't make the electric current which flows through the
LED equal to or more than 150mA±30%.
53 ~ 67mA(at 60mA setting)
