MP2886AGU 概要
A PWM controller is a core building block of multi-phase voltage regulators (VRs) used to power high-current digital loads. It sits between the system management controller and the per-phase power stages (DrMOS/Intelli-Phase), generating the switching waveforms, balancing current between phases, and protecting against over-current, over-voltage, and over-temperature faults. Multi-phase controllers and PWM controllers together form the regulator topology family known as voltage regulators (VRs) inside the broader power management IC hierarchy.
Key features include 6-phase capability (configurable to fewer phases), Open VReg compliant PWM-VID interface, automatic phase shedding and phase add, per-phase current sensing, programmable loop compensation, and comprehensive protection including OVP, OCP, OTP, and UVLO. Digital telemetry via PMBus reports output voltage, output current, input voltage, and temperature for system monitoring. The MP2886AGU minimizes external component count and supports adaptive voltage positioning for GPU/CORE power rails.
The device uses a digital state-machine-based core rather than a traditional analog PWM, with per-cycle current balancing performed by digital signal processing. Loop compensation is implemented in firmware with programmable coefficients, enabling designers to optimize transient response without changing external RC components. The Open VReg PWM-VID bus provides fast dynamic voltage scaling for processor power management and is interoperable with NVIDIA VR specifications.
Typical applications include GPU/CORE voltage regulators for notebook and embedded graphics, server core power, gaming laptop motherboard DC/DC converters, and high-current ASIC/CPU rails that require multi-phase VR solutions with digital telemetry, fast transient response, and compliance with Open VReg/PWM-VID command sets. MPS provides reference designs for several high-current VR topologies.
When designing with this IC, ensure the BOOT and UVLO thresholds are configured for the system bus voltage. Use the MPS Intelli-Phase Designer tool (Intelli-Phase GUI) to configure PMBus parameters, loop coefficients, fault thresholds, and fault response. Do not bypass the PMBus SCL/SDA pull-ups.

主な用途
MP2886AGU の用途: 6 件s: Notebook GPU VR Solution, Server Core/SoC VR, Gaming Laptop Motherboard Power, Workstation Graphics Card Power, High-Current ASIC/DC-DC Rail, Embedded Computing / Industrial SOM.
Notebook GPU VR Solution
The MP2886AGU is purpose-built for notebook discrete GPU voltage regulators. Up to 6-phase operation delivers the high current required by performance mobile GPUs (e.g., 60-200 A peak), while the Open VReg PWM-VID interface accepts dynamic voltage scaling commands from the graphics processor. PMBus telemetry reports current per phase and overall for thermal management in slim chassis; Intelli-Phase stage integration cuts board area by combining MOSFETs and drivers. Designers should size per-phase current against the GPU's typical and burst load profile and use the MPS Intelli-Phase GUI to tune OCP and OVP thresholds.
おすすめ
Server Core/SoC VR
In multi-socket server motherboards, the MP2886AGU drives parallel power stages that supply CPU core and SoC rails at hundreds of amps total. The digital loop provides sub-millisecond transient response to AVS (adaptive voltage scaling) commands from the BMC or PMBus host, and the controller can shed phases at idle to cut light-load losses. Programmable fault thresholds and PMBus status monitoring enable coordinated platform-wide power fault handling. The QFN-40 footprint allows a compact VR block on high-density server PCBs.
おすすめ
Gaming Laptop Motherboard Power
Discrete GPU and CPU VRs on gaming-laptop motherboards benefit from the MP2886AGU's compact footprint, PWM-VID dynamic voltage scaling, and phase shedding. Reference designs from MPS target sub-200 A GPU rails with 4-6 phases and CPU VRs with 2-4 phases, sharing PMBus infrastructure for system power management. The QFN-40 layout and PMBus configuration simplify chassis thermal management by exposing per-phase and total current telemetry for fan control loops.
おすすめ
Workstation Graphics Card Power
Discrete workstation GPUs in desktop and add-in-card form factors demand multiphase VRs with strict regulation under AVS transients. The MP2886AGU's Open VReg PWM-VID compatibility makes it interoperable with workstation GPU controllers that emit standard VID commands. Up to 6 phases, per-phase OCP, and PMBus logging support field debugging and compliance reporting. Board engineers can pair the MP2886AGU with Intelli-Phase parts to fit high-current VR blocks in the area-constrained add-in-card footprint.
おすすめ
High-Current ASIC/DC-DC Rail
The MP2886AGU drives multi-phase VRs for ASICs and DC-DC rails that exceed the current capability of single-phase regulators. Configurable phases (1 to 6) let one controller address a range of load profiles from a few amps (single phase) to over 200 A (six-phase). PMBus telemetry simplifies the surrounding system design by exposing VIN/VOUT/IIN/IOUT/TEMPERATURE for host digital power management. The digital loop removes analog component tolerances and eases EMI optimization across the full load range.
おすすめ
Embedded Computing / Industrial SOM
Industrial-grade system-on-modules and embedded computing boards that integrate NVIDIA-style GPUs or high-performance SoCs can use the MP2886AGU for multi-rail VR management. PMBus and Open VReg PWM-VID interfaces enable embedded firmware to implement adaptive power policies, monitor power quality, and log faults. The -40C to +125C operating range and QFN-40 footprint suit compact, thermally constrained industrial enclosures and long-life product cycles where digital power management adds reliability and observability.

主な差別化要因

設計ノート
Estimated: at full 6-phase operation with peak per-phase Intelli-Phase currents (e.g., 40 A per phase), total package dissipation in the QFN-40 should be confirmed against the datasheet thermal resistance values. Layout should maximize the thermal pad connection to ground pours and use multiple vias on the central thermal pad to extract heat efficiently. Designers should verify with the Intelli-Phase current thermal model when pairing specific MPS power stages.
Place the PMBus SCL and SDA pull-up resistors close to the controller; typical values are 2.2 kohm to 4.7 kohm depending on bus capacitance per PMBus spec. Route the PWM output traces to each Intelli-Phase stage as 50 ohm controlled-impedance traces on a dedicated layer, keeping them short and away from analog feedback traces. Place BOOT/UGATE bias components on the same layer as the controller to minimize parasitic inductance in the high-current gate-drive paths.
Use the MPS Intelli-Phase GUI to configure the digital loop coefficients specific to the chosen power stage and output LC filter. Programmable loop parameters let designers tune transient response without changing external components. Verify with end-to-end simulation or bench load-step measurement; the controller supports firmware field updates via PMBus for tuning production units.
Do not bypass the PMBus pull-ups or SMBAlert line; without them the controller may fail to enumerate on the system PMBus and lose telemetry. Confirm that the PWM-VID host is Open VReg compliant; non-compliant PWM-VID sequences may produce incorrect output voltages. Fault response masks should be reviewed at power-up to avoid masking user-configurable OVP/OCP during early board bring-up.
