630 V driver IC for CFL and TL lamps
Product specification
UBA2021
FEATURES
Adjustable preheat and ignition time
Adjustable preheat current
Adjustable lamp power
Lamp temperature stress protection at higher mains
voltages
Capacitive mode protection
Protection against a too-low drive voltage for the power
MOSFETs.
GENERAL DESCRIPTION
The UBA2021 is a high-voltage IC intended to drive and
control Compact Fluorescent Lamps (CFL) or fluorescent
TL-lamps. It contains a driver circuit for an external
half-bridge, an oscillator and a control circuit for starting
up, preheating, ignition, lamp burning and protection.
