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.
The 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.
