- - Hrs Note 5, 6
Note 1: PWM dimming function can be operated by PWM signal. PWM duty cycle can adjust white Luminance.
(PWM High: ON and PWM Low: OFF)
Note 2: PWM signal can not be floating and pull-down to ground when waiting.
Note 3: Enable (V
LED On/Off
) must be turned on late than V
LED
and PWM Signal.
Note 4: Enable (V
LED On/Off
) must be turned off early than V
LED
and PWM Signal.
Note 5:
If G057QN01 V2 module is driven by high current or at high ambient temperature & humidity condition. The
operating life will be reduced.
