  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. http://www.ti…

  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.…
