UC1871 Overview
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.
UC1871 Key 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
UC1871 Applications
- Smooth 100% Duty Cycle on Buck PWM and 0% to 95% on
