Notes
Why it is interesting: PI design-example reports are unusually complete: transformer construction and winding spreadsheet, full BOM, layout and performance data. MinE-CAP switches bulk-capacitor sections to shrink the input capacitor for universal input, a useful density trick.
Watch out: PDFs are hosted under several power.com subdomains with the same path; the www path is assumed (link-unchecked).
