| FAN7317 LCD Backlight Inverter Drive IC FAN7317 LCD Backlight Inverter Drive IC June 2011 High-Efficiency Single-Stage Power Conversion Wide Input Voltage Range 6V to 24V Backlight Lamp Ballast and Soft Dimming Minimal Required External Components Precision Voltage Reference Trimmed to 2% ZVS Full-Bridge Topology Soft-Start PWM Control at Fixed Frequency Burst Dimming Function Programmable Striking Frequency Open-Lamp Protection Open-Lamp Regulation Arc Protection Short-Lamp Protection CMP-High Protection High-FB Protection Thermal Shutdown 20-Pin SOIC LCD TV LCD Monitor The FAN7317 is a LCD backlight inverter drive IC that controls P-N full-bridge topology by using the new proprietary phase-shift method. The FAN7317 provides a low-cost solution and reduces external components by integrating full wave rectifiers for open-lamp protection and regulation. The operating voltage range of the FAN7317 is wide, so an external regulator isn’t necessary to supply the voltage to the IC. The FAN7317 provides various protections, such as open-lamp regulation, open-lamp protection, arc protection, short-lamp protection, CMP-high protection, and FB-high protection, to increase the system reliability. The FAN7317 provides burst dimming function and analog dimming is possible, in a narrow range, by adding some external components. The FAN7317 is available in a 20-SOIC package.
