The UC3872 is a resonant lamp ballast controller optimized for driving cold cathode fluorescent, neon, and other gas discharge lamps. The resonant power stage develops a sinusoidal lamp drive voltage, and minimizes switching loss and EMI generation. Lamp intensity adjustment is accomplished with a buck regulator, which is synchronized to the external power s.
• Controls Different Types of Lamps:
Cold Cathode Fluorescent, Neon, and Gas Discharge
• Zero Voltage Switching (ZVS) of Push-Pull Drivers
• Accurate Control of Lamp Current
• Variable Lamp Intensity Control
• 1µA Disable Current
• 4.5V to 24V Operation
• Open Lamp Detection Circuitry
