1 / 24 page  August 2009 © 2009 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN7318B • 1.0.0 FAN7318B LCD Backlight Inverter Drive IC 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 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 components 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, open- lamp 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. Ordering Information Part Number Operating Temperature Package Eco Status Packing Method FAN7318BM Rail FAN7318BMX -25 to +85°C 20-Lead, Small Outline Integrated Circuit (SOIC) RoHS Tape & Reel For Fairchild’s definition of Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html.
