The UBA201x is a family of high voltage Integrated Circuit (IC) intended to drive fluorescent lamps with filaments such as Tube Lamps (TL) and Compact Fluorescent Lamps (CFL) in general lighting applications. The IC comprises a fluorescent lamp control module, a half-bridge driver and several protection mechanisms. The UBA2015 parts additionally have a built-in critical conduction mode Power Factor Correction (PFC) controller/driver. The IC drives fluorescent lamp(s) using a half-bridge circuit made of two MOSFETs with a supply voltage of up to 600 V. The UBA201x family of IC's are designed to be supplied by a start-up bleeder resistor and a dV/dt supply from the half-bridge circuit, or any other auxiliary supply derived from the half-bridge or the PFC. The supply current of the IC is low. An internal clamp limits the supply voltage.
