The FAN7318 is a LCD backlight inverter drive IC that
controls P-N 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.
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.
The FAN7318 is available in a 20-SOIC package.
