LTC3634

The ADI Versal AI Core Power Reference Design Board has been tested and proven to power the key rails for the Xilinx Versal AI Core ACAP series. Using a PMBUs Multi Phase DC/DC controller coupled with ADI SilentMOS (ADI version of DrMOS) to deliver up to 240A of output current.

The ADI LTC3888-1 is an 8 Phase PMBUs DC/DC controller that is coupled with the LTC7051 ADI SilentMOS to provide a flexible and scalable design that can be tailored as needed for both higher and lower power applications by adding or subtracting the LTC7051 ADI SilentMOS.

ADI Key Power Management Features for Versal PRIME XCXM1802 for Minimum Rails / PL Performance

• 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.
• LT8607 is a compact, high efficiency, high speed 750mA synchronous monolithic.
• LTC3634 is a single chip solution for DDR rails providing VDD, VTT, and Vref in a monolithic solution.
