Board Layout
A complete Allegro ATX and BTX demo board layout
file and schematics are available by request at
www.onsemi.com and can be viewed using the Allegro
Free Physical Viewer 15.x from the Cadence website
http://www.cadence.com/.
Close attention should be paid to the routing of the sense
traces and control lines that propagate away from the
controller IC. Routing should follow the demo board
example. For further information or layout review contact
ON Semiconductor.
