※ Dimming principle for PWM style output
‧Dimming is achieved by varying the duty cycle of the output current.

Duty cycle of additive 10V PWM signal dimming input
Note : 1. Min. duty cycle of output current is about 8% and the output current is not defined when 0%< Iout<8%.
2. The duty cycle of output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.
