FAN7318
LCD Backlight Inverter Drive IC
Features
Description
The FAN7318 is a LCD backlight inverter drive IC that
controls P-N half-bridge topology.
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
The FAN7318 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 FAN7318 is wide, so an
external regulator isn’t necessary to supply the voltage to
the IC.
Soft-Start
PWM Control at Fixed Frequency
Analog Dimming Function
Burst Dimming Function
The FAN7318 provides various protections, such as
open-lamp regulation, open-lamp protection, short-Lamp
protection, CMP-high protection, and FB-high protection,
to increase the system reliability. The FAN7318 provides
burst dimming and analog dimming.
Programmable Striking Frequency
Open-Lamp Protection
The FAN7318 is available in a 20-SOIC package.
