AME9003 Datasheet Ccfl Backlight Controller

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: .. AME, Inc. AME9003 y inar m i l Pre CCFL Backlight Controller n.

General Description

The AME9003 is AME’ s next generation direct drive CCFL controller.

Like its cousins, the AME9001 and AME9002, the AME9003 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.

The AME9003, like 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” .

Key Features

  • a soft start AND soft finish on each dimming cycle edge in order to minimize any audible vibrations during the dimming function. The AME9003 also includes features such as, 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 AME9003 1 2 3 4 5 6 7 8 9 10 11 12 AME9003 1. VREF 2. CE 3.
