UBA2070
Datasheet
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. The UBA2070 provides the drive function for the two discrete MOSFETs. Besides the drive function the UBA2070 also includes the level-shift circuit, the oscillator function, a lamp voltage monitor, a current control function, a timer function and protections.
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.
