Three Different Buck Converter Circuits to Convert 12V to 1.2V at >6A Load Current Reference Design

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 converterSwitched-capacitor buck converter: multi-phase buck converter: and single POL buck converterLight-Load efficiency available in all solutionsSolutions with sub 2mm heightOn-board transient testers for controlled: high slew rate transient loads
Applications
  • Modem (cable/DSL/GFAST)
  • Baseband unit (BBU)
  • Edge router
  • Intra-DC interconnect (metro)
  • Optical network terminal unit (ONT)
  • Inter-DC interconnect (long-haul
  • submarine)
  • Core router
  • Performance client
  • High performance computing
  • Active antenna system mMIMO (AAS)
  • Gateway (xDSL/cable)
  • Indoor backhaul
  • Campus & branch switches
  • Cell site gateway router
  • Multi-access edge computing (MEC)
  • Data center switch
  • Macro remote radio unit (RRU)
Product Categories
  • Power management
