OR:  

The UBA2024 is a family of high-voltage monolithic Integrated Compact Fluorescent Lamp (CFL) drivers for a large range of lamp powers. Specific versions are optimized for 230 V and 110 V 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.

Features and benefits

  • High integration level enabling a small form factor electronic ballast CFL Lamp
  • Integrated bootstrap diode
  • Integrated low-voltage supply
  • Integrated half-bridge power transistors

Applications

  • Designed for electronically self-ballasted CFL Lamps
  • Driver for any kind of half-bridge configured load up to 15 W

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.
