Description

The UBA2024 is a high-voltage monolithic integrated circuit made in the EZ-HV SOI process. The IC is designed for driving CFL lamps in a half-bridge configuration.

The IC UBA2024 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.
