A cold cathode fluorescent lamp (CCFL) driver circuit comprising: more than one ballast, at least one of which is connected to at least an electrode at one end of each of more than one CCFL; and a low-impedance power supply powering said CCFL through said ballast and having an output impedance lower than the total impedance of said www.doorway.ru by: BiCMOS Cold Cathode Fluorescent Lamp Driver Controller datasheet (Rev. C) UCC/3 UCC/3 UCC/3. DESCRIPTION. Design goals for a Cold Cathode Fluorescent Lamp (CCFL) converter used in a notebook computer or portable application include small size, high effi- ciency, and low cost. The UCC/3 CCFL controllers provide the neces- sary circuit . A second driver is electrically coupled to the second terminal of the illumination unit, for applying AC voltages to the second terminal in such a manner that the AC voltages at the first terminal and the second terminal are out of phase.

Feb. 15, Cold-cathode fluorescent display backlights are compared/contrasted to LED backlights, and the differences in driver circuits for both are discussed. Tom Novitsky. A light transmitting container is used to house a cold cathode fluorescent lamp (CCFL) to reduce heat loss and to increase the luminous efficiency of the lamp. An electrical connector configuration is connected to an electrode of the lamp and adapted to be electrically and mechanically connected to a conventional electrical socket. A cold cathode fluorescent lamp (CCFL) driver circuit comprising: more than one ballast, at least one of which is connected to at least an electrode at one end of each of more than one CCFL; and a low-impedance power supply powering said CCFL through said ballast and having an output impedance lower than the total impedance of said CCFLs.

CCFL Lamp Controllers, Texas Instruments. Cold Cathode Fluorescent Lamp (CCFL) converters used in a notebook computer or portable application include small. Once the CCFL discharge starts, such an inverter circuit operates to step the voltage at the secondary side of the inverter transformer down to about V.
