UC3871 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.
UC3871 Key Features
- 1µA ICC when Disabled
