Hi
I have an application that requires +/-15V power supply for set of op-amps that consume in total less than 10mA (using low power op-amps)
I have only 5V power supply on board. I was exploring two options for deriving power supplies for op-amp
1. 5V to +/-15V boost converter
2. DC-DC Converter.
Option1 requires some external components besides the IC and wanted integrated solution and opted for option 2.
DC-DC converter for such low power is available only on isolated versions. Non isolated versions are bulky and high power. Can I simply connect two grounds of isolated dc-dc converter?
