FAN7317
LCD BACKLIGHT INVERTER DRIVE IC

General 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.

TThe 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.
