AME9002 - CCFL Backlight Controller

General Description

The AME9002 is AME’s next generation direct drive CCFL controller.

Key Features

  • such as soft start, duty cycle dimming control, dimming control polarity selection, undervoltage lockout and fault detection. It is designed to work with input voltages from 7V up to 24V. When disabled the circuit goes into a zero current mode. n Pin Configuration 24 23 22 21 20 19 18 17 16 15 14 13 AME9002 1 2 3 4 5 6 7 8 9 10 11 12 AME9002 1. VREF 2. CE 3. SSC 4. RDELTA 5. FAULTB 6.

AME, Inc. AME9002 www.DataSheet4U.com y nar i m i l Pre CCFL Backlight Controller n General Description The AME9002 is AME’s next generation direct drive CCFL controller. Like its cousin, the AME9001, the AME9002 controller provides a cost efficient means to drive single or multiple cold cathode fluorescent lamps (CCFL), driving 3 external MOSFETs that, in turn, drive a wirewound transformer that is coupled to the CCFL. However the AME9002 includes extra circuitry that allows for a special one second start up period wherein the voltage across the CCFL is held at a higher than normal voltage to allow older tubes (or cold tubes) a period in which they can “warm up”.
