Dual-phase compact reference design for 2.7 V 60 A for telecommunications

Overview

TopologyBuck Converter
Input voltage12 V
Switching frequency300-2000 kHz
Output 12.7 V / 60 A
IC revisionA

Description

This reference design uses only 2 ICs in a stacked configuration to provide 2.7 V at 60 A in a compact form factor. Both an all ceramics output capacitors version and a low ESR polymer output capacitors version were demonstrated to meet requirement of less than 3% undershoot for a step load from 2 A to 60 A in less than 1 microsecond. Internal compensation simplifies the design process. Design includes on-board high speed dynamic load tester, output ripple probe interface and test points for a stability analyzer.

Features

  • 2.7 V at 60 A with only two 5-mm by 7-mm ICs
  • Meets less than 3% voltage undershoot for step load from 2 A to 60 A in under 1 microsecond
  • Verified to meet this performance with either all ceramic out capacitors or with polymer output capacitors
  • Rich test interface, including on-board, high speed dynamic load

Typical applications

  • Enterprise Storage, SSD
  • ASIC, SoC, FPGA, DSP Core, and I/O Rails
  • Wireless and Wired Communications Infrastructure Equipment / Enterprise Servers, Switches, and Routers
