Thermal Derating

Designers using modular power converters for their systems know how critical a thermal derating curve is to the success of their design. No offense to marketing people, but the bulleted features on the front page of the datasheet such as those claiming “up to 50-A output current” are a good indication of the general capabilities of the power converter, but can lead the designer down a dark path of no return if used to compare to another manufacturer’s datasheet in selecting a converter that will work in their design. Datasheet front page specs can be different from manufacturer to manufacturer — look closely and understand the conditions at which specifications and claims are made. Dig deeper!
