Overview

PMP11184 is a chipset solution for high current ASIC core rail regulation. It utilizes TPS53647 4-phase controller for 120A high current rail, which employs  DCAP+ control for fast transient response and TI's proprietary AutoBalance for tight steady and dynamic phase-to-phase current balance. It also utilizes TPS40428 dual controller for dual 30A rails. Both controllers drive TI NexFET smart power stages for high power density and efficiency. PMBus capability and on-board NVM enable easy design, configuration, and customization, with telemetry of output voltage, current, temperature, and power.

Features
  • Detached layout enables flexible placement
  • High efficiency 91% at 1V/120A, 300kHz, 12Vin
  • Excellent thermal performance (72C FET temperature at full load with 200LFM air flow)
  • Combined ripple and transient response within +/-2%.
  • Full PMBus telemetry of output voltage, current, power and temperature
