UBA2024P中文资料恩XP数据手册PDF规格书

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.
