1 / 16 page  © 2006 Fairchild Semiconductor Corporation www.fairchildsemi.com January 2007 FAN7311 Rev. 1.0.6 FAN7311 LCD Backlight Inverter Drive IC Features 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 Applications LCD TV LCD Monitor Description 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 fluo- rescent lamp (CCFL) and the transformer's characteris- tics. The FAN7311 uses a new patent-pending phase- shift control.
