Photonic Sourcing

Regulated
Hi Reliability, Isolated, DC-DC Converters

Low Profile 0.35" Height Up to 4.5 Watts
No Heat Sink or Electrical Derating Required

This series of encapsulated converters come in 100 different models. The units feature single and isolated dual outputs. They will operate over a temperature range of -25º C to +70º C. No heat sink is required. These units are excellent for applications where the input voltage varies ±10% and the output must be held to ±0.2%. The output voltage is maintained to within 0.5% from no load to full load.
