Product data sheet
1. General description
The UBA2211 family of integrated circuits are a range of high voltage monolithic ICs for driving pact Fluorescent Lamps (CFL) in half-bridge configurations. The family is designed to provide easy integration of lamp loads across a range of burner power and mains voltages.
2. Features and benefits
2.1 System integration
- Integrated half-bridge power transistors
- UBA2211A: 220 V mains; 13.5 ; 0.9 A maximum ignition current
- UBA2211B: 220 V mains; 9 ; 1.35 A maximum ignition current
- UBA2211C: 220 V mains; 6.6 ; 1.85 A maximum ignition current
- Integrated bootstrap diode
- Integrated high voltage supply
2.2 Burner current
- Adjustable current controlled preheat mode enables the preheat time (tph) to be set
- RMS current control
2.3 Burner lifetime
- Current controlled preheat with adjustable preheat time and preheat current
- Minimum glow time control to support cold start
- Lamp power independent from mains voltage variations
- Lamp inductor saturation protection during ignition
2.4 Safety
- Saturation Current Protection (SCP)
- Over Temperature Protection (OTP)
- Capacitive Mode Protection (CMP)
- Overpower control
- System shutdown when the burner fails to ignite
