  Ambient Temperature
 

The still-air temperature in the immediate vicinity of a DC/DC Converter, measured at 100 mm from the converter.

 
  Burn-in
 

The process in which a new DC/DC Converter is operated at full load by the manufacturer before shipment to the customer (24 hours at full load; nominal input voltage/12 hours load ON/OFF; input min. to max.).

 
  Case
 

Small container serving as packaging for the power converter.

 
  Case Temperature
 

Temperature of the case when the DC/DC Converter is operating under normal conditions.

 
  Cross Regulation
 

In a multiple output converter, the percent voltage change at one output caused by the load change on another output.

 
  DC/DC Converter
 

Electronic device that converts an input DC voltage into an output DC voltage.

The output voltage is usually different than the input voltage, but can be identical in certain applications.

 
  Derating
 

The reduction in output power at high temperatures.

 
  Dielectric Strength
 

Maximum voltage the converter can withstand without breaking down. Also referred to as Hi-Pot Test.

 
  Distributed Power
 

This system of power distribution replaces the more traditional Central Power Systems. Standard power converter modules are used at board level.

 
  Dual Stage Input Filter
 

Superior method of filtering both input  current and voltage  to provide  the cleanest possible signal on the line (PI filter & L-type filter).
