FAN7318MX

LCD背光逆变器驱动IC LCD Backlight Inverter Drive IC

Description

The FAN7318 is a LCD backlight inverter drive IC that controls P-N half-bridge topology.

The FAN7318 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 FAN7318 is wide, so an external regulator isn’t necessary to supply the voltage to the IC.
