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.
