The PB23 is for powering phantom powered microphones with 48VDC. Since the unit uses a 100KHz switching power supply there is no audio noise generated. It has an output pull down resistors so it will work with any mixer.

I rather would do it myself.
I think I try to make with MC34063. Now I wait for components...

The manual has a schematic. For about $25 on ebay, you could get the box with all the connectors and change the circuit to your design. Evaluate both circuits and see if you can improve the 48V converter.
