DC-Transformer 105-3.3

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 6 ... 36 VDC
  • very high efficiency: up to 95%
  • input surge voltage: 38 VDC
  • output voltage / max. output current: 3.3 VDC / 1.5 ADC

Applications

The 105-3.3 is a classic POL converter (point of load). Mostly it is used on "motherboards" with DC supply voltages of 12V or 24V to generate the local 3.3V supply. The 3.3V output voltage can also be generated with an input 5V supply voltage.
