Abstract
DC--DC power converters are an integral and critical component of telecommunications products. As a key component, the reliability of these devices has direct impact on quality of the products. Many of the converters utilized in telecommunications products are standard "off the shelf" commercial units, available from a wide variety of suppliers. With the recent proliferation of the use of these devices, former qualification methods had proven incapable of assuring the quality and reliability requirements for a telecom environment. Disclosed is the current setup, test, statistical analysis and failure analysis methods used to assess DC--DC power converter design quality and reliability.
