GENERAL DESCRIPTION
The UBA2021 is a high-voltage IC intended to drive and
control Compact Fluorescent Lamps (CFL) or fluorescent
TL-lamps. It contains a driver circuit for an external
half-bridge, an oscillator and a control circuit for starting
up, preheating, ignition, lamp burning and protection.
