| FAN7318 LCD Backlight Inverter Drive IC FAN7318 LCD Backlight Inverter Drive IC March 2009 Features High-Efficiency Single-Stage Power Conversion Wide Input Voltage Range 6V to 30V Backlight Lamp Ballast and Soft Dimming Minimal External Components Required Precision Voltage Reference Trimmed to 2% Half-Bridge Topology Soft-Start PWM Control at Fixed Frequency Analog Dimming Function Burst Dimming Function Programmable Striking Frequency Open-Lamp Protection Open-Lamp Regulation Short-Lamp Protection CMP-High Protection FB-High Protection Thermal Shutdown 20-Pin SOIC Applications LCD TV LCD Monitor The FAN7318 is a LCD backlight inverter drive IC that controls P-N half-bridge topology. The FAN7318 provides a low-cost solution and reduces external components by integrating proprietary wave rectifiers for open-lamp protection and regulation. The operating voltage range of the FAN7318 is wide, so an external regulator isn’t necessary to supply the voltage to the IC. The FAN7318 provides various protections, such as open-lamp regulation, open-lamp protection, short-Lamp protection, CMP-high protection, and FB-high protection, to increase the system reliability. The FAN7318 provides burst dimming and analog dimming. The FAN7318 is available in a 20-SOIC package.
