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.
