ADI Key Power Management Features for Versal ACAP XCXM1802 for Optimized Efficiency

  • Proposed Solution implements new LTC3887-1/LTC7051 combo
  • LTC3887-1 is a PMBus 2-phase, 2 loop, current mode controller. PMBus commands allow Vin, Vout, current, temperature, and fault status read back.
  • LTC7051 is new Silent Switcher 2 ADI MOS capable of delivering increased DC load while switching at higher frequencies. Increased DC load allows for decreased phase count and higher current density. Increased Fsw allows for increase bandwidth and excellent transient response.
  • LTC3636 is dual 6A, controlled on-time current mode monolithic (integrated FETs). Provides high performance compact solution for auxiliary rails.
  • LTC3634 is a single chip solution for DDR rails providing VDD, VTT, and Vref in a monolithic solution.
  • LTC3634 is a single chip solution for DDR rails providing VDD, VTT, and Vref in a monolithic solution.

电路描述

The Prime series is the foundation and the mid-range of the Versal platform, serving the broadest applicability across multiple markets. These applications include 100G to 200G networking equipment, network and storage acceleration in the data center, communications test equipment, broadcast, and aerospace & defense. The series integrates mainstream 58G transceivers and optimized I/O and DDR connectivity, achieving low latency acceleration and performance across diverse workloads.
