Description
The FAN7317B is a LCD backlight inverter drive IC that controls P-N full-bridge topology using a new propriety phase-shift method.
The FAN7317B 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 FAN7317B is wide, so an external regulator isn’t necessary to supply the voltage to the IC.
