Managing DC/DC thermals in high-current, high-ambient temperature applications

Description

February 21, 2020
Most integrated-FET DC/DC converters do not have the ability to operate at high ambient temperatures without significant de-rating of the output current. As a result, many designers sacrifice solution size and build their power supply around a multiphase buck controller to manage heat. Enter TPS546D24A. With its unparalleled thermal performance, the integrated-FET TPS546D24A buck converter produces a full 40A at 85C with smaller solution size and greater simplicity than multiphase controllers.
