NOTES:
A “C” designator indicates the aluminum shell is connected internally to the common
output return pin.
An “F” designator indicates the aluminum shell is floating and is not connected to any
part of the converter circuitry.
An “M” designator indicates the aluminum shell is connected internally to the main
output return pin.
An “N” designator indicates the aluminum shell is connected internally to the negative
input voltage pin.
A “P” designator indicates the aluminum shell is connected internally to the positive
input voltage pin.
