Features - High-Efficiency Single-Stage Power Conversion - Wide Input Voltage Range: 6V to 30V - Backlight Lamp Ballast and Soft Dimming - Minimal External ponents 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 - Over-Voltage Protection - Short-Lamp Protection - CMP-High Protection - Thermal Shutdown - 20-Pin SOIC .. Applications - - LCD TV LCD Monitor Description The FAN7318B is a LCD backlight inverter drive IC that controls P-N half-bridge topology. The FAN7318B provides a low-cost solution and reduces external ponents by integrating proprietary wave rectifiers for open-lamp protection and regulation. The operating voltage range of the FAN7318B is wide, so an external regulator isn’t necessary to supply the voltage to the IC. The FAN7318B provides various protections, such as open-lamp regulation, over-voltage protection, openlamp protection, short-Lamp protection, CMP-high protection, to increase the system reliability. The FAN7318B provides burst dimming and analog dimming. The FAN7318B is available in a 20-SOIC package.
