General description

The UBA2016A/15/15A are high voltage Integrated Circuits (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, half-bridge driver, built-in critical conduction mode Power Factor Correction

(PFC) controller/driver and several protection mechanisms. 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 UBA2016A/15/15A 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.
