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 re-
quiring an additional supply, as in LCD displays. When disabled the IC draws
only 1
µA, 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 stress. An open lamp is detected on the completion of a soft-start
cycle.
The Buck controller is optimized for smooth duty cycle control to 100%, while
the flyback control ensures a maximum duty cycle of 95%.
Other features include a precision 1% reference, under voltage lockout, flyback
current limit, and accurate minimum and maximum frequency control.
