INFINEON TECHNOLOGIES offers several switching converters serving applications with extended requirements like supply for 32-bit μC and airbag applications. In our portfolio you can find step-up (Boost) and step-down (Buck) DC/DC converters as well as DC/DC converters cascaded internally with linear regulators and trackers.

 

  • Step-up and step-down converters
  • High-efficiency regulators
  • Wide supply voltage operation range
  • Very low current consumption operation
  • Suitable for standard 12V / 24V PowerNets
  • Disable function for main output
  • Output undervoltage reset with delay
  • Short-circuit protection
  • Overtemperature protection
  • Wide ambient operation range - 40°C up to 150°C
