Basics of board-mounted dc/dc converter reliability

January 15, 2021 By Jeff Shepard Leave a Comment

The reliability of board-mounted dc/dc converters is important to understand and quantify. It’s a measure of the frequency of system or device failures as a function of time. Reliability is the observed failure rate and is defined as either the time between two failures (in hours), called the Mean Time Between Failures (MTBF), or the […]

EMC/EMI design and the use of board-mount dc/dc converters

January 14, 2021 By Jeff Shepard Leave a Comment

EMC/EMI

Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) are system-level considerations that have implications for power system design, especially when multiple board-mounted dc/dc converters are used in a distributed power architecture (DPA). EMC/EMI is a multidimensional consideration and includes differential- and common-mode noise on both the input and output of the converter radiated and conducted noise […]

Thermal management considerations for board-mounted dc/dc converters

January 13, 2021 By Jeff Shepard Leave a Comment

thermal management

System-level thermal design is equally important to the electrical specifications of board-mounted dc/dc converters. And the growing use of variations on a distributed power architecture (DPA) increases the complexity of thermal design. A single multiple-output ac/dc power supply is used to power the various loads in a conventional power architecture. The use of a centralized […]

Specifying board-mounted dc/dc converters

January 12, 2021 By Jeff Shepard Leave a Comment

The specification of board-mounted dc-dc converters is an important and detailed process. Correctly implemented, it results in a cost-effective solution that meets all the needs of the application. Incorrectly specified dc/dc converters can result in a more costly device than necessary and/or a device that is not suited for the application. This FAQ will review […]
