Selecting the Correct Level of DC-DC Converter for Your Application

Most power systems for high reliability applications can be constructed from standard power modules. The typical scenario requires various DC output voltages and power levels and is usually met with standard DC-DC converters, EMI filters and accessory modules. A modular power system can be developed quicker and at lower cost than a full custom approach. This is true even for critical applications and reliability can often be as high as or higher than that of a custom design.

Critical applications range from undersea to military ground to commercial and military avionics to deep space. DC-DC converters, point of load converters, EMI filters and other power modules are offered by various manufacturers, all claiming high reliability. The question is, how do you know what level of quality and reliability you are getting, and how do you select the correct level for your application?
