The FAN7316 is a LCD backlight inverter drive IC that controls N-N half-bridge topology. The FAN7316 can also drive push-pull topology.

The FAN7316 provides a low-cost solution by integrating the external open-lamp protection circuit. The operating voltage of the FAN7316 is wide, so the FAN7316 doesn’t need an external regulator to supply the voltage to the IC. The FAN7316 has the internal bootstrap driver, so the external fast recovery diode can be avoided.

The FAN7316 provides various protections, such as open-lamp regulation, arc protection, open-lamp protection, short-circuit protection, and CMP-high protection to increase the system reliability. The FAN7316 provides analog dimming, burst dimming, and burst dimming polarity selection functions.

The FAN7316 is available in a 20-SOIC package.
