General description

The UBA2017/UBA2017A 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 and several protection mechanisms. The IC drives fluorescent

lamps using a half-bridge circuit made of two MOSFETs with a supply voltage of up to

600 V.

The UBA2017/UBA2017A are 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. The

supply current of the IC is low. An internal clamp limits the supply voltage.
