I have a DC voltage in the range 9-15 Volts available to supply the multi-rail power supply TPS65381-Q1, which is fine, but unfortunately I need galvanic isolation, i.e. an isolated DC-DC converter with a transformer. Any suggestions for a suitable device/application will be appreciated. It should be capable of supplying current corresponding to the current limit (1.4A) of the pre-regulator of the TPS65381-Q1.
