Description
The FAN7317B is a LCD backlight inverter drive IC that
controls P-N full-bridge topology using a new propriety
phase-shift method.
The FAN7317B 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 FAN7317B is wide,
so an external regulator isn’t necessary to supply the
voltage to the IC.
The FAN7317B provides protections such as open-lamp
regulation,
protection to increase the system reliability. The
FAN7317B provides a burst-dimming function and
analog dimming is possible, in a narrow range, by adding
external components.
The FAN7317B is available in a 20-pin SOIC package.
