UBA2024P/N1

NXP  UBA2024P/N1  芯片, CFL驱动器, 半桥, 8DIP

The is a high-voltage monolithic integrated Compact Fluorescent Lamp CFL Driver for a large range of lamp powers. Specific versions are optimized for 230V and 110V mains supplies. The product family integrates full CFL controller functionality with high voltage half-bridge transistors. All products in the UBA2024 family are pin-to-pin compatible enabling a single application design covering a wide range of power ratings. 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.
