Features & Benefits

ADI Key Power Management Features for Versal PRIME XCXM1802 for Low Voltage

  • 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.
  • LTC3644 is a quad 1.25A output, high efficiency synchronous monolithic capable of switching up to 2.25MHz.
  • LTC3634 is a single chip solution for DDR rails providing VDD, VTT, and Vref in a monolithic solution.

Parts Used
