MPQ2977

Dual-Rail, Digital 6-Phase Controller

with PMBus Interface,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ2977 is a dual-rail, multi-phase digital

voltage regulator (VR) controller for autonomous

driving applications. The MPQ2977 can work

with MPS’s Intelli-Phase^TMproducts to complete

the multi-phase VR solution with minimal

external components. The MPQ2977 is scalable

up to six phases between two rails.



Dual-Rail Digital PWM Controller with Up to

6-Phase Operation

PMBus Compliant for Configurations and

Monitoring

Built-In Multiple-Time Programmable (MTP)

Memory to Store Custom Configurations

Automatic Loop Compensation

Fewer External Components than

Conventional Analog Controller

Automatic Phase-Shedding (APS) with and

without Discontinuous Conduction Mode

(DCM) to Improve Overall Efficiency

Phase-to-Phase Active Current Balancing

Input Voltage (V_IN) and Output Voltage

(V_OUT) Monitoring



The on-chip, multiple-time programmable (MTP)

memory

stores

and

restores

device



configurations. Device configurations and fault

parameters can be configured or monitored

using the PMBus interface. The MPQ2977 can



monitor and report the output current (I_OUT

)

through the Intelli-Phase^TMcurrent-sense (CS)

output.



Output Current (I_OUT) Monitoring

Regulator Temperature Monitoring

Under-Voltage Lockout (UVLO), Over-

Voltage Protection (OVP), Under-Voltage

Protection (UVP), Over-Current Protection

(OCP), and Over-Temperature Protection

(OTP)

Cyclic Redundancy Check (CRC) for MTP

Transformation

Separate EN for Each Rail

The MPQ2977 is based on unique, digital, multi-

phase nonlinear control to provide fast transient

response to a load step with minimal output

capacitors. With only one power loop control

method for both the steady state and load

transient response, power loop compensation is

simple to configure.



The MPQ2977 is available in a TQFN-40

(6mmx6mm) package.



Digital, Configurable Load Line

Available in a TQFN-40 (6mmx6mm)

Package



Available in AEC-Q100 Grade 1

APPLICATIONS



Autonomous Driving System-on-Chips

(SoCs)



Infotainment Systems
