High-Efficiency, Single-Stage Power Conversion
Wide Input Voltage Range: 6V to 28V
Backlight Lamp Ballast and Soft Dimming
Minimal Required External Components
Precision Voltage Reference Trimmed to 2%
ZVS Full-Bridge Topology
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.
Soft-Start
PWM Control at Fixed Frequency
Burst Dimming Function
The FAN7317B provides protections such as open-lamp
regulation, open-lamp protection, and short-lamp
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.
Dynamic Contrast Ratio Function
Programmable Striking Frequency
Open-Lamp Protection (OLP)
Open-Lamp Regulation (OLR)
Short-Lamp Protection (SLP)
Thermal Shutdown (TSD)
The FAN7317B is available in a 20-pin SOIC package.
