NXP UBA2021

Beschreibung

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.

Eigenschaften

• Adjustable preheat and ignition time.
• Adjustable preheat current.
• Adjustable lamp power.
• Lamp power independent from mains voltage variations.
• Overpower protection.
• Lamp temperature stress protection at higher mains voltages.
• Capacitive mode protection.
• Protection against a drive voltage that is too low for the power MOSFETs.

Typische Anwendungen

• Fluorescent TL lamps
• Fluorescent TL lamps
