- DN-75 Using the UC3871 and UC3872 Resonant Fluorescent Lamp Drivers in FloatingPDF, 160 Kb, Datei veröffentlicht: Sep 5, 1999
The UC3871 and UC3872 family of resonant lamp drivers contains all of the necessary control circuitry to implement a highly efficient, cold-cathode. fluorescent back-light driver. This design note de-scribes how to modify the circuit to accommodate a floating-lamp topology. - U-141 Resonant Fluorescent Lamp Converter Provides Efficient and CompactPDF, 210 Kb, Datei veröffentlicht: Sep 5, 1999
The UC3871 IC 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. The switching frequency of all outputs is synchronized to the resonant frequency of the external passive network, which provides Zero Voltage Switching (ZVS) on the push-pull drivers. This paper describ - U-148 Dimmable Cold-Cathode Fluorescent Lamp Ballast Design Using the UC3871PDF, 380 Kb, Datei veröffentlicht: Sep 5, 1999
The UC1871 family of ICs 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. This application note describes how to design a resonant cold-cathode fluorescent lamp converter and liquid crystal display (LCD) bias supply using the UC3871. This note discusses a design meth
