We've done several products with the TPS62130A, with acceptable EMI performance. We have followed the TI recommendations for laying out the components around the part.
The current product is showing excessive EMI, possibly due to the required cable configuration.
An article in the Analog Applications Journal (slyt614) showing how to layout the TPS62130A includes a layout that includes a snubber, but says nothing about the values for R & C.
Most articles that I have found on designing a snubber circuit start with the output capacitance of the switch. This is not given in the TPS62130A data sheet.
Can you provide the output capacitance of the TPS62130A switch? Or provide other help in determining appropriate snubber values?
Thanks
