Description
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.
