General description

The UBA2024P is a high-voltage monolithic integrated circuit. The Integrated Circuit (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.
