NXP Semiconductors UBA2017A
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.| Part No. | UBA2017A |
