Right Topology for DC/DC Converter Help

Other Parts Discussed in Thread: UCC2803, UCC28700

Hallo! I'm new here!

I'm looking for a isolated dc to dc converter with 10-15V input and 7-15V output.

The output Power varies between 0.5W and 7W.

I was thinking about a Flyback Converter but I want to avoid the opto-isolator. The converter musn't be regulated just if the output Volatge matches the input Voltage. If the best topology for this application ist the flyback converter, then it must be primary side regulated.

Thanks in Advance!

  • Hi,

    The UCC2803 can work from a 5V Vcc but requires an opto feedback for use in a regulated flyback topology. All the primary side regulated flyback controllers such as the UCC28700 require a higher Vcc.

    I don't think we have a controller for this application.

    Regards

    Peter
