Resonant Fluorescent Lamp Driver 20-PLCC 0 to 70

The UC1871 Family of IC???s is optimized for highly efficient fluorescent lamp control. An additional PWM controller is integrated on the IC for applications requiring an additional supply, as in LCD displays. When disabled the IC draws only 1uA, providing a true disconnect feature, which is optimum for battery powered systems. The switching frequency of all outputs are synchronized to the resonant frequency of the external passive network, which provides Zero Voltage Switching on the Push-Pull drivers. Soft-Start and open lamp detect circuitry have been incorporated to minimize component stre...
