Reference Design - DDR3/DDR4 Power Supply with 5V Input and 10A Load for Industrial PCs


Design files


This reference design shows a universal power supply solution for DDR3 and DDR4 memory. A synchronous Buck converter provides an output voltage of 1.35V for a 9A load in DDR3L configuration. A linear regulator provides a second voltage of 0.675V for a 2A load.

  • Built and tested
  • Solution for DDR3, DDR3L, DDR3U and DDR4 by adjusting just a single resistor
  • High efficiency
  • Very good dynamic performance
  • Headroom for transients
  • Very low ripple
