The TIDA-01451 reference design’s functionality emulates the power distribution of Set Top Boxes. By using integrated load switches to control power rails: each rail can be turned on or off depending on the needs and wants of the user. Turning off rails that are not being used reduces power loss and facilitates meeting energy compliance standards: such as Energy Star. An eFuse placed at the input can manage Hot Plug transients and protect downstream DC/DC converters from an input voltage that is too high or too low: reducing end equipment return rate.
