The pinout (Pxx) and case (Cxx) designations (typically P65 or C59) refer to
a generic family of closely related information. It may not be a single pinout
or unique case outline. Please be aware of small details (such as Sense pins,
Power Good pins, etc.) or slightly different dimensions (baseplates, heat
sinks, etc.) which may affect your application and PC board layouts. Study the
Mechanical Outline drawings, Input/Output Connection table and all footnotes
very carefully. Please contact Murata Power Solutions if you have any ques-
tions.
