Yes there was a bug in the Linkswitch-PH Buck spreadsheet. We have corrected this and the patch is due to roll out around Nov 13th.

In the meantime if you send me your specs or better still, attach the old (problematic) PIXls file I can run the same design through the corrected version of spreadsheet and send it back to you.
