Isolated Type DC-DC converters

Our isolated type DC-DC converters are ultra small, low noise, high isolation and have a wide range of operating temperatures.
Our Isolated Type DC‐DC converter BR‐LB Series, applying TCT circuit, achieves low noise of 3mVpp and is employed in ATS (Automatic Train Stop) devices.

Ultra low noise isolated type DC‐DC converter "BL series"

Low output ripple noise DC‐DC converters are required for analog circuits of measuring equipment, analyzers, diagnostic imaging equipment and the like.
We have BL series isolated type DC‐DC converters available for these applications. The BL series have satisfied both low ripple noise and high efficiency output by adopting a resonant circuit.

-Features-

  • Ultra low ripple noise : 5mVp‐p
  • Isolation voltage : AC500V
  • Wide range of input voltage
  • Reducing LDO loss
  • Small mounting space
  • Metallic shield case
