Description

PMP11438 is a vehicle used to compare three different power solutions for converting a 12V bus to 1.2V at 6-10A. The 1.2V output voltage is applicable to DDR4 memory applications. Each solution offers an advantage in either full load efficiency, light load efficiency, density, height, transient response, or some combination of these.

Features
  • Two 1.2V/10A power converters and one 1.2V/6A converter
  • Switched-capacitor buck converter, multi-phase buck converter, and single POL buck converter
  • Light-Load efficiency available in all solutions
  • Solutions with sub 2mm height
  • On-board transient testers for controlled, high slew rate transient loads
