Half-bridge power IC for CFL lamps

Rev. 04 — 17 September 2009

Product data sheet

1. General description

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.
