Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 7 ... 35 VDC
  • very high efficiency: up to 97%
  • peak input voltage: 37 VDC
  • output voltage / max. output current: 24.0 VDC / 8.0 ADC


DC/DC boost converter 24V 200W. Short-circuit proof buck and boost DC charging converter for primary use in supercapacitor powered autonomous systems with output-side backup battery. The LEX version has the advantage of a very low input voltage of down to 5V. Output-side integrated reverse polarity protection diodes enable battery charging. Customizing DC/DC converters as DC/DC Converter 12V, DC/DC Converter 13.8V or DC/DC Converter 27V and much more can be realized.
