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
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 stage’s resonant frequency. Suitable for automotive and battery powered applications, the UC3872 draws only 1μA when disabled.
Soft start and open lamp detect circuitry have been incorporated to minimize component stresses. Open lamp detection is enabled at the completion of a soft start cycle. The chip is optimized for smooth duty cycle control to 100%.
Other features include a precision 1.2% reference, undervoltage lockout, and accurate minimum and maximum frequency control.
