| FAN7311 LCD Backlight Inverter Drive IC December 2007 FAN7311 LCD Backlight Inverter Drive IC - High-Efficiency Single-Stage Power Conversion - Wide Input Voltage Range 5V to 25.5V - Backlight Lamp Ballast and Soft Dimming - Reduced Number of Required External Components - Precision Voltage Reference Trimmed to 2% - ZVS Full-Bridge Topology - Soft-Start Capability - PWM Control at Fixed Frequency - Analog and Burst Dimming Function - Programmable Striking Frequency - Open-Lamp Protection - Open-Lamp Regulation - 20-Pin SSOP/SOIC/DIP - LCD TV - LCD Monitor The FAN7311 provides all the control functions for a series parallel resonant converter as well as a pulse width modulation PWM controller to develop a supply voltage. Typical operating frequency range is between 30kHz and 250kHz, depending on the cold cathode fluorescent lamp CCFL and the transformer's characteristics. FAN7311 uses a new patented phase-shift control. 20-SSOP 20-SOIC 20-DIP Ordering Information Part Number FAN7311G FAN7311GX FAN7311M FAN7311MX FAN7311N Package 20-SSOP 20-SSOP 20-SOIC 20-SOIC 20-DIP Operating Temperature Range -25°C to 85°C Packing Method Rail Tape & Reel Rail Tape & Reel Rail All packages are lead free per JEDEC J-STD-020B standard.
