1. General description
2. Features and benefits
2.1 System integration
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
specifically designed to provide easy integration of lamp loads across a range of burner
power and mains voltages.
Patented technologies and integrated protection types:
UBA2211
Half-bridge power IC family for CFL lamps
Rev. 2.1 — 7 March 2011
Integrated half-bridge power transistors
Integrated bootstrap diode
Integrated high voltage supply
Preheat state:
– Preheat applications: Adjustable current controlled preheat mode technology
– Non-preheat applications: Glow-time control minimizes electrode damage just after
Saturation Current Protection (SCP): This protection is active during ignition
ensuring the lamp inductor can operate at the saturation current limit without
exceeding the current ratings of the integrated half-bridge power transistors.
RMS current control: The IC internally calculates the RMS current and changes the
frequency (f
active in the burn state ensuring a constant half-bridge burner current and IC
dissipation. The nominal half-bridge burner current is set using the sense resistor
(R
OverTemperature Protection (OTP) and Capacitive Mode Protection (CMP):
Overtemperature and capacitive mode protection monitor the application ensuring, in
non-standard conditions, correct system shutdown and a safe condition at the
burner’s end-of-life.
