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