28Chapter 1 General Description This inverter is designed for the CCFL of α 550 14.1” LCD which are using on the α 550 notebook. We use two signals to control the LCD brightness. One is the Enable, which turn on and turn off the birightness of LCD. The other is the PWM, which tune the brightness by modulating the duty cycle. This inverter uses open loop control circuit and meets with safety requirements. Features 1. +5V Fixed input voltage 2. Birghtness adjustment by PWM duty cycle 3. Current...
