MP2886A

Digital, Multi-Phase PWM Controller

with PMBus and PWM-VID

DESCRIPTION

FEATURES

The MP2886A is a digital, multi-phase, pulse-

width modulation (PWM) controller with a digital

PWM-VID interface that is compatible with

NVIDIA’s Open VReg specification. The

MP2886A works with MPS’ Intelli-Phase

products to complete the multi-phase voltage

regulator (VR) solution with minimal external

components. The MP2886A can be configured

with up to 6-phase operation.



Programmable Multi-Phase up to 6 Phases

PWM-VID Interface Compatible with NVIDIA

PMBus/I²C Compliant (1MHz Bus Speed)

Pin Programmable for PMBus Address

Built-In EEPROM to Store Custom

Configurations



Switching Frequency Range 200kHz to

5MHz



Automatic Loop Compensation

Fewer External Components than A

Conventional Analog Controller

Best Transient Performance with Non-

Linear Digital Control

Flexible Phase Assignment

Auto-Phase Shedding to Improve Overall

Efficiency

The MP2886A provides an on-chip EEPROM to

store and restore device configurations. Device

configurations and fault parameters can be

easily programmed or monitored via the

PMBus/I²C interface. The MP2886A can monitor

and report the output current through the CS

output from the Intelli-Phase products.



Phase-to-Phase Active Current Balancing

with Programmable Offsets for Thermal

Balance

Output Voltage/Current, Input Voltage/

Power Monitoring

Regulator Temperature Monitoring

VIN UVLO, Output OVP/UVP, OCP, OTP

with No Action, Latch, Retry, or Hiccup

Mode Options

Detecting for Intelli-Phase MOSFET Fault

Type and Auto-Record to EEPROM

Digital Load-Line Regulation

The MP2886A is based on a unique, digital,

multi-phase, non-linear control and provides fast

transient response to the load transient with

minimal output capacitors. With only one power-

loop control method for both steady state and

load transient, the power loop compensation is

very easy to configure.



The MP2886A is available in a QFN-40

(5mmx5mm) package.



Available in an RoHS Compliant QFN-40

(5mmx5mm) Package

APPLICATIONS



Graphic Card Core Power

Server Core Power

Telecom and Networking Systems



Base Stations
