MP2853

Dual-Loop, Digital, Multi-Phase Controller

with PMBus^TMInterface for AMD SVI2

DESCRIPTION

FEATURES

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.

•

Multi-Phase, Dual-Output, Digital Controller

AMD SVI 2.0 Compliant

Supports 3-Bit PVID Mode

PMBus^TM/I²C Compliant (1MHz Bus Speed)

Pin Programmable for PMBus^TMAddress

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 Components than a

Conventional Analog Controller

Best Transient Performance with Non-

Linear Digital Control

Flexible Phase Assignment for Dual Rails

Auto-Phase Shedding to Improve Overall

Efficiency

•

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

PMBus^TM/I²C interface. The MP2853 can

monitor and report output current through the

CS output from Intelli-Phase products.

•

The MP2853 is based on a unique, digital,

multi-phase, non-linear control to provide fast

transient response to the load transient with

minimal output capacitors. With only one

power-loop control method for both steady state
