Optional Functions
The A-Series 7-15W DC/DC Converters offer numerous electrical/ mechanical
options. Per the Ordering Guide on page 2, the trailing "A" (A-Series) in each
part number pertains to the base part number. Part-number suffi xes are added
after the "A," indicating the selection of standard options. The resulting part
number is a "standard product" and is available to any customer desiring that
particular combination of options. As described below, selecting certain options
will result in the installation of additional pins in certain locations.

Adaptations
There are various additional confi gurations available on A-Series 7-15W DC/DCs.
Because designating each of them with a standard part-number suffi x would
result in an unmanageable matrix of part numbers, such are designated by
MPS and assigned 5-digit "part-number suffi xes.

the amount of trim added since excessive positive trim may exceed the
overvoltage protection. Excessive negative trim may interfere with proper
