FAN7317B Backlight Inverter Drive
January 2010
FAN7317B
Backlight Inverter Drive
Features
High-Efficiency, Single-Stage Power Conversion Wide Input Voltage Range: Backlight Lamp Ballast Soft Dimming Minimal Required External Components Precision Voltage Reference Trimmed Full-Bridge Topology Soft-Start Control Fixed Frequency Burst Dimming Function Dynamic Contrast Ratio Function Programmable Striking Frequency Open-Lamp Protection (OLP) Open-Lamp Regulation (OLR) Short-Lamp Protection (SLP) Thermal Shutdown (TSD) 20-Pin SOIC
Description
FAN7317B backlight inverter drive that controls full-bridge topology using propriety phase-shift method. FAN7317B provides low-cost solution reduces external components integrating full wave rectifiers open-lamp protection regulation (patent pending). operating voltage range FAN7317B wide, external regulator isn't necessary supply voltage FAN7317B provides protections such open-lamp regulation, open-lamp protection, short-lamp protection increase system reliability. FAN7317B provides burst-dimming function analog dimming possible, narrow range, adding external components. FAN7317B available 20-pin SOIC package.
