In general, for AC-DC power supplies and DC-DC converters, output derating (or power loss due to heating) reference curves are provided based on a combination of various conditions, such as operating voltage, temperature, and airflow. End-product designers can select power supplies based on this information. Studying the derating ensures power system safety, heat dissipation, and reliability.

The design of the power supply network in an integrated system is often one of the last factors the engineering team considers. However, not all applications can accommodate an indefinite variety and number of voltage rails. Achieving a power supply (whether from supply lines or batteries) that is efficient, low-noise, and tightly regulated is complex, making this a critical hardware design decision.
