Half-bridge power IC family for CFL lamps

Rev. 3 — 26 August 2011

Product data sheet

1. General description

The UBA2211 family of integrated circuits are a range of high voltage monolithic ICs for

driving Compact 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 (t_ph) 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)

 OverTemperature Protection (OTP)

 Capacitive Mode Protection (CMP)

 Overpower control

 System shutdown when the burner fails to ignite
