Two-Sided Layout Reference Design to Increase Power Density With DC/DC Converters
Description
This reference design demonstrates the correct way to design a two-sided DC/DC layout in an effort to achieve higher power-supply density. The design guide highlights common mistakes and how to avoid them: along with test results showing that proper implemenation of the TPS54824 device in a two-sided layout does not hinder performance. If the 8-A output of the TPS54824 buck converter is too much: this design can also use the TPS54424 device: a 4-A: pin-to-pin compatible alternative.
