MP2853 - Digital Multi-Phase Controller

General Description

The MP2853 is a dual-loop, digital, multi-phase controller that provides power for the core of the AMD SVI 2.0 platform.

The MP2853 can work with MPS Intelli-Phase products to complete the multi-phase voltage regulator (VR) solution with minimal external components.

Key Features

  • Multi-Phase, Dual-Output, Digital Controller.
  • AMD SVI 2.0 Compliant.
  • Supports 3-Bit PVID Mode.
  • PMBusTM/I2C Compliant (1MHz Bus Speed).
  • Pin Programmable for PMBusTM Address.
  • Built-In EEPROM to Store Custom Configurations.
  • Switching Frequency Range from 200kHz to 3MHz.
  • Digital Load-Line Regulation.
  • Over-Clocking Mode by Adding Offset to Output Voltage.
  • Automatic Loop Compensation.
  • Fewer External Com.

MP2853 Dual-Loop, Digital, Multi-Phase Controller with PMBusTM Interface for AMD SVI2 DESCRIPTION The MP2853 is a dual-loop, digital, multi-phase controller that provides power for the core of the AMD SVI 2.0 platform. The MP2853 can work with MPS Intelli-Phase products to complete the multi-phase voltage regulator (VR) solution with minimal external components. The MP2853 can be configured with up to 4-phase operation for Rail 1 and up to 2-phase operation for Rail 2. The MP2853 provides an on-chip EEPROM to store and restore device configurations. Device configurations and fault parameters can be programmed easily or monitored via the PMBusTM/I2C interface. The MP2853 can monitor and report output current through the CS output from Intelli-Phase products.
