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.
