ICB2FL03G

Overview

Smart ballast IC for UV-C disinfection lamps

The smart ballast controller for UV-C disinfection lamps (ICB2FL03G) comes in a slim SO-16 package. It is tailored for cost-performance optimized applications operating UV-C lamps. The ICB2FL03G integrates all functions required to operate UV-C disinfection lamps such as preheat-, ignition- and run-mode and protection features. Digital mixed-signal power control is employed enabling speedy, cost-effective and stable ballast designs with a minimum number of external components. Reliable and robust high-voltage isolation is achieved using Infineon’s proprietary Coreless Transformer Technology (CLT).

Summary of Features

  • Integrated critical conduction mode PFC stage with enhanced dynamic PFC performance over wide load range
  • Intelligent digital-/mixed-signal lamp inverter control
  • Integrated high-voltage level-shift half-bridge driver
  • Optimized for UV-C ballasts
  • Drives up to 2 lamps in serial connection with few external components required
  • Built-in protection functions such as over-voltage protection (OVP) and over-current protection (OCP)
  • Adjustable end-of-life detection in multi-lamp topologies and detection of capacitive mode operation
  • Able to handle lamp chokes with high saturation behavior
  • Special in-circuit test mode for faster test time
  • Parameters set with resistors only
  • Separate adjustable levels of lamp overload and rectifier effect detection (EoL1, EoL2)
  • Self-adapting dead time adjustment of the half-bridge driver
  • Highly accurate timing and frequency control over wide temperature range (-25 to 125 °C)

Benefits

  • Reduced BOM cost by optimized lamp choke size
  • Halving the time for key tests such as end-of-life detection and preheat/operation modes
  • Reduced system cost and improved ballast stability
  • Suitable for dimming & multi-power ballasts
  • Enables ballast compatibility with a wider range of lamp types
  • Lamp can automatically restart following surge events and handle correctly EOL events
  • Eases design of multi-power ballasts and reduces EMI
  • Reliable, stable ballast designs

Potential Applications

  • UV-C lamps for disinfection
