FAN7310, LCD Backlight Inverter Driver, 20-SSOP

The FAN7310-SMD is a Power Management IC designed for LCD backlight inverter applications, particularly those using Cold Cathode Fluorescent Lamps (CCFLs). It provides all the necessary control functions for a series-parallel resonant converter while also integrating a Pulse Width Modulation (PWM) controller to regulate the supply voltage. With its soft dimming, soft start, and open-lamp protection features, it ensures high efficiency and reliable operation in LCD backlighting systems.

• High-Efficiency Power Conversion – Supports single-stage power conversion for LCD backlight applications.
• Wide Input Voltage Range – Operates from 5V to 24V, making it compatible with various power systems.
• PWM Control with Analog and Burst Dimming – Provides precise dimming control for brightness adjustment.
• ZVS Full-Bridge Topology – Zero Voltage Switching (ZVS) enhances efficiency and reduces power loss.
• Soft Start Function – Ensures a controlled startup to prevent damage and extend component lifespan.
• Open Lamp Protection & Regulation – Prevents circuit damage due to open lamp conditions.
