Description
The UC3872 is a resonant lamp ballast controller designed for driving cold cathode fluorescent, neon, and gas discharge lamps. It utilizes zero voltage switching (ZVS) of push-pull drivers to minimize switching loss and EMI generation. The controller features accurate lamp current control, variable lamp intensity adjustment, and a low disable current of 1μA. It operates within a voltage range of 4.5V to 24V and incorporates open lamp detection circuitry.
