Hi,
I want to build a +15V and -15V from the TPS61170 (already used in the design). The application note slua288 based on the UCC3803D is interesting for that.
I just don't understand the RC placed in parallel with the output diode of the application (please see the attached file). At first, I thought it was a snubber, but not really! A snubber would between the SW node and the GND, right?
Any idea? It may be related to the (seems to be old) UCC3803D design itself.
Best Regards,
Denis
