There is nothing which prevents the TPS62740 from being used an an inverter, so you can order an EVM and see if it works for your application.
From this reference design, http://www.ti.com/tool/pmp9752 , the TPS62120 still has decent efficiency (for an…
Part Number: TPS62122 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi Team,
I have a customer who is trying to use the TPS62122 as an inverting buck boost to go from +3.3V to -3.3V (50mA). I took a look at this application…
Thanks for explaining. Is the anode powered from another voltage or from GND?
Here are 2 TI reference designs, which further explain these types of solutions. You might take a look at the lower power and lower input voltage TPS62120/2.

The TPS62120 is a good low power converter for inverting applications similar to this reference design: http://www.ti.com/tool/pmp9752
Many customers would add an LDO after the output to make a 'cleaner' supply, but this may not be necessary.…
