Abstract
►CCFL is commonly used for LCD screen as backlight
►It requires several to teens of hundred volts of AC for its operation
►In usual application a DC-AC inverter is required to power it
►In the past, analog PWM controller is dominating in DC-AC inverter
►With the lowered cost and higher processing power of MCU it is
possible to replace the analog controller with added flexibility in
control algorithm and functionality
►This training will cover different implementation of CCFL controller
with an 8 pin MCU – MC9S08QD4
