Part Number: TPS54060A Other Parts Discussed in Thread: TPS54060EVM-590 , We use this device for a +/-15V power supply, similar to the TPS54060EVM-590, nominal input voltage 24V.
We are using the TPS54060A for several years now. We received a new batch…
The evm and app note may work for you. It generates a +/- output from a 24V input, but it also can work down at 5V.

Rob,
It looks like what you really need is a DC/DC converter because the TL7660 is only a solution for low power and low voltage conversion. The link posted below is one of the two parts that meets the requirements of +14V in and -14V out at 100mA…
