UBA2024  
Half-bridge power IC for CFL lamps  
Rev. 6.2 — 1 November 2010  
Product data sheet  
1. General description  
The UBA2024 is a family of high-voltage monolithic Integrated Compact Fluorescent  
Lamp (CFL) drivers for a large range of lamp powers. Specific versions are optimized for  
230 V and 110 V mains supplies. The product family integrates full CFL controller  
functionality with high voltage half-bridge transistors. All products in the UBA2024 family  
are pin-to-pin compatible enabling a single application design covering a wide range of  
power ratings.  
The IC features a soft start function, an adjustable internal oscillator and an internal drive  
function with a high-voltage level shifter for driving the half-bridge.  
To guarantee an accurate 50 % duty cycle, the oscillator signal is passed through a divider  
before being fed to the output drivers.  
2. Features and benefits  
„ The common feature set includes:  
‹ high power efficiency  
‹ a high integration level with low component counts enabling small form factor  
electronic ballast  
‹ integrated bootstrap diode  
‹ soft start function  
‹ minimum glow time control  
‹ integrated low-voltage supply  
‹ adjustable operating frequency as a result of the embedded oscillator  
‹ an accurate 50 % duty cycle provided by an embedded oscillator signal  
‹ integrated half-bridge power transistors  
‹ an internal drive function with a high-voltage level shifter up to 550 V (300 V for the  
UBA2024BP and UBA2024BT)  
3. Applications  
„ Driver for any kind of half-bridge configured load up to 23 W, provided that the  
maximum junction temperature is not exceeded  
„ Designed for electronically self-ballasted CFL lamps
