Overview
UBA2017/UBA2017A 600 V fluorescent lamp driver with linear dimming function Rev.
2 — 15 May 2012 Product data sheet 1.
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.
