UC2872 Datasheet (Unitrode) - Resonant Lamp Ballast Controller

UC2872, Resonant Lamp Ballast Controller

The UC3872 is a resonant lamp ballast controller optimized for driving cold cathode fluorescent, neon, and other gas discharge lamps.

The resonant power stage develops a sinusoidal lamp drive voltage, and minimizes switching loss and EMI generation.

Lamp intensity adjustment is accomplished with a b
