MP2926

Triple-Loop, Digital, Multi-Phase

Controller with PMBus Interface

DESCRIPTION

FEATURES

The MP2926 is a triple-loop, digital, multi-phase

controller that provides power for the memory

and SoC. The MP2926 can work with MPS’s

Intelli-Phase^TMproducts to complete the multi-

phase voltage regulator (VR) solution with

minimal external components. The MP2926 can

be configured with up to 2-phase operation for

each rail.



Multi-Phase, Triple-Output, Digital Controller

PMBus/I²C Compliant (1MHz Bus Speed)

PVID Mode Available

Pin Configurable for PMBus Address

Built-In NVM to Store Custom

Configurations



Switching Frequency Range 200kHz to

3MHz



Automatic Loop Compensation

Fewer External Components than a

Conventional Analog Controller

Best Transient Performance with Nonlinear

Digital Control

Flexible Phase Assignment for Triple Rails

Automatic Phase-Shedding to Improve

Overall Efficiency

The MP2926 provides an on-chip non-volatile

memory (NVM) to store and restore device

configurations. Device configurations and fault

parameters can be easily programmed or

monitored via the PMBus/I²C interface. The

device can monitor and report output current

through the current-sense (CS) output from

Intelli-Phase^TMdevices.



Phase-to-Phase Active Current Balancing

with Configurable Offsets for Thermal

Balance

Input and Output Voltage, Current, and

Power Monitoring

Regulator Temperature Monitoring

V_INUVLO, Output OVP/UVP, OCP, OTP

with No Action, Latch, or Hiccup Mode

Intelli-Phase^TMFault Diagnosis

Auto-Records the VR Fault Type to the

NVM

The MP2926 is based on unique, digital, multi-

phase, nonlinear control to provide a 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

easy to configure.



The device is available in

(5mmx5mm) package.

QFN-40



Digital Load-Line Regulation

Overclocking Mode by Adding Offset to

Output Voltage



RoHS-Compliant

Available in a QFN-40 (5mmx5mm)

Package
