| Features |
• 1µA ICC when Disabled • PWM Control for LCD Supply • Zero Voltage Switched (ZVS) on Push-Pull Drivers • Open Lamp Detect Circuitry • 4.5V to 20V Operation • Non-saturating Transformer Topology DESCRIPTION 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 1µA, providing a true disconnect feature, which is optimum for battery powered systems. The switching frequency of all outputs are synchronized to the r... |
