*1 Wide variation of LED VF increases loss at the driver, which results in high package temperature. Therefore the board needs to be designed with
attention paid to heat radiation..
*2 Current amount per 1ch
*3 Larger set values increase thermal loss, resulting in high package temperature. Therefore pay attention to heat radiation when setting.
*4 Peak current: Avoid such use as 400 mA keeps on flowing at PWM DUTY of 100%. Average current needs to not exceed 200mA.
● For the function of increasing current, see the explanation of LED_LV terminal.
