Gen. Notes: Order of Power On should be CCFL Current → VIN → PWM ON/OFF.
Inverter Module generates high voltage and should not be touched during operation.
Note 1: PWM ON/OFF Control Pin is connected to VIN when PWM ON/OFF Control is always 100% Duty Cycle.
Note 2: CCFL Current is 1.2 mA minimum when VIN(CURRENT) is 4.1 V.
CCFL Current is 2.5 mA maximum when VIN(CURRENT) is 2.5 V.
