FAN7310 LCD Backlight Inverter Drive Integrated Circuit

May 2007
- High-Efficiency, Single-Stage Power Conversion - Wide Input Voltage Range 5V to 24V - Backlight Lamp Ballast and Soft Dimming - Reduce External Components - Precision Voltage Reference Trimmed to 2% - ZVS full-bridge topology - Soft-Start Feature - PWM Control at Fixed Frequency - Analog and Burst Dimming Function - Synchronizable Switching Frequency with External

Signal - Open-Lamp Protection - Open-Lamp Regulation - 20-Pin SSOP
- LCD TV - LCD Monitor

The FAN7310 provides all the control functions for a series parallel resonant converter and contains a pulse width modulation PWM controller to develop a supply voltage. Typical operating frequency range is between 30kHz and 250kHz, depending on the CCFL and the transformer's characteristics. The FAN7310 has a patent-pending on phase-shift control.
