FAN7317
LCD Backlight Inverter Drive IC
Features
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.
High-Efficiency Single-Stage Power Conversion
Wide Input Voltage Range: 6V to 24V
Backlight Lamp Ballast and Soft Dimming
Minimal Required External Components
Precision Voltage Reference Trimmed to 2%
ZVS Full-Bridge Topology
Soft-Start
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.
PWM Control at Fixed Frequency
Burst Dimming Function
Programmable Striking Frequency
Open-Lamp Protection
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.
