Calculator Simplifies Programming the Burst Dimming Stagger on the
DS3994 Cold-Cathode Fluorescent Lamp (CCFL) Controller

Abstract: The DS3994 is a 4-channel controller for cold-cathode fluorescent lamps (CCFL) that backlight liquid crystal
displays (LCDs) in TV and PC monitor applications. The device uses burst dimming to control the brightness of the lamps. A
unique feature allows the start of the burst dimming sequence for each of the four channels to be staggered independently. A
set of four nonvolatile registers allows the user to program the stagger for each channel. A c
