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%
  • peak input 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.

Features

  • non-isolated step-down converter
  • very low input ripple
  • continous no load and short circuit proof
  • for ambient temperatures of -40°C up to +85°C
  • thermal shutdown at +110°C
  • for passive loads only
  • integrated EMI input filter
  • no derating of power
  • compact aluminium case
  • robust design
  • unipolar output voltage
  • non-isolated output
