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. Page 2 December 1999 TOKO, Inc.
