UBA2070 - CCFL ballast driver IC

General Description

The UBA2070 is a high voltage integrated circuit for driving electronically ballasted Cold Cathode Fluorescent Lamps (CCFL) at mains voltages up to 277 V (RMS) (nominal value).

The circuit is made in a 650 V Bipolar CMOS DMOS (BCD) power logic process.

Key Features

  • Current controlled operation.
  • Adaptive non-overlap time control.
  • Integrated high voltage level shift function.
  • Power-down function.
  • Protected against lamp failures or lamp removal.
  • Capacitive mode protection.
