Two-Sided Layout Reference Design to Increase Power Density With DC/DC Converters


Design files


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.

  • Input Range: 4.5 V to 17 V, 1.8 VOUT at 8-A IOUT
  • Peak Efficiency: 94.7% at 5 VIN, 2-A IOUT
  • Load Regulation: < ±0.04%
  • Switching Frequency: 700 kHz
  • Total Solution Size: 280 mm2

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
