power supply - Step up DC voltage from 12-24V to 60V

I need to provide a 60V/1A power source from a 12-24V input, -40 to 85 degC temperature range. Parametric searches for DC/DC converters at a couple online vendors don't seem to be turning up much.

I'd prefer a simple chassis mount module of some kind, really.

Are there (readily available) DC/DC converters out there that satify these criteria? If not, how can I go about designing something that will work?
