Description
The FAN7317 is a LCD backlight inverter drive IC that
controls P-N full-bridge topology by using the new
patented phase-shift method.
The FAN7317 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 FAN7317 is wide, so
an external regulator isn’t necessary to supply the
voltage to the IC.
The FAN7317 provides various protections, such as
open-lamp regulation, open-lamp protection, arc
protection, short-lamp protection, CMP-high protection,
and FB-high protection, to increase the system reliability.
The FAN7317 provides burst dimming function and
analog dimming is possible, in a narrow range, by adding
some external components.
The FAN7317 is available in a 20-SOIC package.
