LONDON The European Power Supply Manufacturers Association (EPSMA) has started circulating a guideline document to help design engineers understand better the complexities and importance of the thermal performance of board-mounted DC/DC converters in a host of applications.
Bernhard Erdl, Chairman of the EPSMA, commented: "Thermal problems can be a major factor behind any lack of reliability of board-mounted DC/DC converters in the field. This guide should prove a valuable resource to engineers designing in this area."
The guide stresses that measuring the thermal performance of an on-board converter can create many problems, as it depends largely on how the converter is actually used in the application.
The booklet which can be downloaded here, examines the different methods of thermal measurement for board-mounted DC/DC converters.
It then outlines the thermal testing procedures for these products, covering the four main application scenarios: heat dissipation through the pins, use of additional heatsinks, thermal coupling to a chassis, and rack-mounting.
