On/Off Enable Control Ground Bounce Protection
To improve reliability, if you use a small signal transistor or other external
circuit to select the Remote On/Off control, make sure to return the LO side
directly to the –Vin power input on the DC/DC converter. To avoid ground
bounce errors, do not connect the On/Off return to a distant ground plane or
current-carrying bus. If necessary, run a separate small return wire directly to
the –Vin terminal. There is very little current (typically 1-5 mA) on the On/Off
control however, large current changes on a return ground plane or ground bus
can accidentally trigger the converter on or off. If possible, mount the On/Off
transistor or other control circuit adjacent to the converter.

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.
