CCFL Transformer Application Note
Cold Cathode Fluorescent Lamps (CCFLs) are used to illuminate Liquid
Crystal Displays (LCDs). The LCD display is used in laptop computers, gas
pumps, automobiles, test equipment, PDAs and medical instruments.
CCFLs are small, efficient and inexpensive. The lamp must be driven by a
specialized power supply. High sinusoidal AC voltage is needed to start the
lamps, but once started, the voltage drops to a lower level. CCFL circuits
are usually powered from a low voltage DC source of 5-12V. The DC to AC
power supply needs a transformer to change low DC input voltage to high
sinusoidal AC voltage.
