The UBA2024 is a high-voltage monolithic Integrated Circuit (IC). The IC is designed for driving Compact Fluorescent Lamps (CFL) in a half-bridge configuration.
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.
