1 / 3 page  January 2008 © 2007 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN7317 • 1.0.2 FAN7317 LCD Backlight Inverter Drive IC Features 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 Applications LCD TV LCD Monitor Description The FAN7317 is a LCD backlight inverter drive IC that controls P-N full-bridge topology by using the new patented 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 (patent pending). 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. Ordering Information Part Number Package Operating Temperature Packing Method FAN7317M 20-SOIC -25 to +85°C RAIL FAN7317MX 20-SOIC -25 to +85°C TAPE & REEL All packages are lead free per JEDEC: J-STD-020B standard. Protected under U.S. patent nos. 5,652,479 and 7,158,390. |
