The FAN7318B 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 FAN7318B is wide, so an external regulator isn’t necessary to supply the voltage to the IC. The FAN7318B provides various protections, such as open-lamp regulation, over-voltage protection, openlamp protection, short-Lamp protection, CMP-high protection, to increase the system reliability. The FAN7318B provides burst dimming and analog dimming. The FAN7318B is available in a 20-SOIC package.
