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


Design files


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.

  • 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
