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\x92s resonant frequency. Suitable for automotive and battery powered applications, the UC3872 draws only 1\xB5A 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. View datasheet View product folder
