谐振灯镇流器控制器 Resonant Lamp Ballast Controller
DESCRIPON
The UC3872 is a resonant lamp ballast controller optimized for driving cold cathode fluorescent, neon, and other gas discharge lamps. The res onant power stage develops a sinusoidal lamp drive voltage, and mini mizes switching loss and EMI generation. Lamp intensity adjustment is accomplished with a buck regulator, which is synchronized to the external power stage’s resonant frequency. Suitable for automotive and battery powered applications, the UC3872 draws only 1µA when disabled.
