I have no way of determining what will or will not problem because you
have not defined the sensitivity of your application. 'Little circuit'
doesn't tell me much. However the converter scheme you describe is about
as good as it gets. I would make sure that primary and secondary grounds
are NOT connected together. Otherwise I would not expect a problem.

I have a little circuit that runs off the 12 volt power supply in a vehicle.
Part of the circuit needs a bipolar supply, and I was planning to use one of
the cute little DC / DC converters to output maybe 5 watts off + and - 15
volt DC. The converter I have selected has a PI filter on the input,
accepts a wide input range (8-18 Volts), and is regulated. My question is
whether alternator hash will be a problem, Will I need a choke and
capacitor on the front end of this gizmo like we used to put on car radios
and the like? Or will the converter do its job OK with raw vehicle DC?
Thanks in advance.
