note 1IREF resistance value(k) 66 ÷ [LED set value (mA)] × 4.7(k) , also [LED set value]  
is possible to set with 22mA ~ 66mA.  
(note 2) Set a lower limit value 1.1V to be only 1ch in 3ch, and use the other 2ch by 2.0V or more  
with LED_Vf.  
(note 3) External load: The total line resistance value of CPOUT pin ~ LED anode and LED  
cathode ~ LED_X pin within 2Ω.  
(note 4) 50% setting is an upper bound when 3ch becoming turning on at the same time.
