— LC D B a FAN7318A cklight LCD Backlight Inverter Drive IC Invert Features Description e r D
ƒ High-Efficiency, Single-Stage Power Conversion The FAN7318A is a LCD backlight inverter drive IC that ƒ Wide Input Voltage Range: 6V to 30V controls P-N half-bridge topology.
rive IC
ƒ Backlight Lamp Ballast and Soft Dimming The FAN7318A provides a low-cost solution and reduces ƒ Minimal External Components Required external components by integrating proprietary wave rectifiers for open-lamp protection and regulation. The ƒ Precision Voltage Reference Trimmed to 2% operating voltage range is wide, so an external regulator ƒ Half-Bridge Topology isn’t necessary to supply voltage to the IC. ƒ Soft-Start ƒ The FAN7318A provides various protections, such as PWM Control at Fixed Frequency open-lamp regulation, over-voltage protection, open- ƒ Analog Dimming Function lamp protection, short-lamp protection, and CMP-HIGH ƒ Burst Dimming Function protection, to increase the system reliability. The ƒ Programmable Striking Frequency FAN7318A provides burst dimming and analog dimming. ƒ Open-Lamp Protection (OLP) The FAN7318A is available in a 16-SOIC package. ƒ Open-Lamp Regulation (OLR) ƒ Over-Voltage Protection (OVP) ƒ Short-Lamp Protection (SLP) ƒ CMP-High Protection (CHP) ƒ Thermal Shutdown (TSD) ƒ 16-Pin SOIC Package
