Mingjiada Supplies and Recycles MPS MPC22168-170: 16V/170A Bi-phase Intelli-Module™ Power Module—In-Stock Solutions and Inventory Liquidation Channels

As AI servers and high-performance computing platforms continue to evolve toward “higher current, higher power density, and smaller board footprint,” MPS (Monolithic Power Systems) Intelli-Module™ series power modules have become one of the mainstream choices for powering CPUs, GPUs, and ASIC cores. The MPC22168-170, a dual-phase model in this series with outstanding current-handling capabilities, can deliver up to 170A (85A per phase) of continuous current at a 16V input. It integrates DrMOS and inductors within an LGA-72 package, balancing high power density with design simplification. Leveraging nearly three decades of experience in both the supply and recycling of electronic components, Mingjiada Electronics offers long-term, genuine off-the-shelf supply and high-value buyback services for the MPC22168-170 to server solution providers, distributors, and end-user manufacturers, helping customers establish flexible channels for both “securing available components” and “disposing of surplus inventory.”

MPC22168-170 Product Positioning: A Dual-Phase Intelli-Module™ Designed for Core Server Power Supply

The MPC22168-170 belongs to the MPS Intelli-Module™ product line and is a dual-phase, non-isolated, high-efficiency buck power module. Its core design philosophy integrates a driver MOSFET (DrMOS) and a power inductor within a single package, thereby achieving high power density within a limited board footprint. It is specifically designed for core power supply applications in servers and computing platforms. The module provides two output channels that can operate independently or in parallel. Within a wide input voltage range of 4V to 16V, each phase can deliver 85A of continuous current, with a total output capability of 170A when both phases are operated in parallel or at full load independently.

Compared to discrete DrMOS-plus-inductor solutions, the MPC22168-170’s modular design reduces the number of external components and layout area while maintaining MPS’s consistent advantage in current density within the server power supply sector. For high-density boards that need to power multiple ASICs or GPU cores, this package-level integration results in shorter power paths and more controllable parasitic parameters.

Key Specifications and Packaging

The key electrical and physical parameters of the MPC22168-170 are as follows:

Manufacturer: Monolithic Power Systems (MPS)

Product Type: Dual-phase non-isolated buck power module (Intelli-Module™)

Input Voltage Range (V_IN): 4V to 16V

Maximum Output Current (I_OUTX): 170 A (85 A per phase)

Output Voltage Range: 0.5 V to 2 V

Switching Frequency Range: 500 kHz to 1.5 MHz

Package Type: LGA-72 (9 mm × 9.9 mm × 7.65 mm)

Typical Weight: 3.5 g

Mounting Method: Surface Mount

Environmental Certifications: Lead-free, Halogen-free, RoHS-compliant

The LGA-72 package accommodates a complete two-phase power stage within a 9 mm × 9.9 mm footprint, and its 7.65 mm height falls within the acceptable range for both air-cooled and liquid-cooled server boards. For OAM accelerator cards, PCIe accelerator cards, and motherboard VR zones—where space is limited but current demands continue to rise—the combination of this package size and 170A output capability holds clear engineering significance.

Key Features: QST Noise Reduction + Flexible Two-Phase Configuration + Precise Telemetry

The technical value of the MPC22168-170 lies not only in its current rating but also in the balance it achieves between noise, flexibility, and observability.

Quiet Switcher™ (QST) technology is MPS’s signature technology in server power modules. Through QST, the MPC22168-170 effectively limits peak voltages at switching nodes, reducing switching ringing and electromagnetic interference (EMI). This enhances system reliability across a switching frequency range of 500 kHz to 1.5 MHz and minimizes design iterations in downstream stages caused by high-frequency switching noise. In applications sensitive to EMI margin, such as server motherboards, the noise reduction benefits provided by QST directly translate to a reduction in the number of filtering components and the complexity of their layout.

The dual-phase independent/parallel capability provides system designers with the flexibility to configure the module according to load requirements: the two output channels can either serve different voltage domains or load points separately, or be connected in parallel to achieve a higher single-channel current output. This “one module, two uses” feature reduces the variety of component selections and the complexity of inventory management in multi-phase expansion and load sharing strategies.

Accu-Sense™ current and temperature sensing provide the module with real-time telemetry capabilities. Accu-Sense™ precisely monitors the inductor current in each phase, supporting current sharing and overcurrent protection; temperature sensing reports junction temperature (T_J) in real time, facilitating system thermal management and over-temperature derating. The module also integrates overcurrent protection (OCP) and over-temperature protection (OTP), and indicates the fault type via the PWMx pin using different resistance values: in the event of an overcurrent fault, PWMx is connected to AGND via a 10 kΩ resistor; in the event of an over-temperature fault, it is connected to AGND via a 20 kΩ resistor; and in the event of a SW-to-PGND short circuit, it is pulled up to VCC via a 1 kΩ resistor. This fault-coding mechanism provides the system controller with distinguishable hardware-level fault information without requiring an additional communication bus.

Typical Application Scenarios

The MPC22168-170’s 170A output capability and LGA-72 package positioning mean its applications are concentrated in the core power supply segments of servers and computing platforms:

Servers and Computing Platforms: Provides high-current, high-efficiency POL-level power supply solutions for server CPUs, GPUs, and ASIC core power supplies.

FPGA/ASIC Core Power Supplies: Meets the high-current and fast transient response requirements of field-programmable gate arrays and application-specific integrated circuits.

Graphics Card Core Regulators: Provides high-power-density voltage regulation for the GPU cores of high-performance graphics cards.

AI Acceleration Cards and Data Centers: Supports the power supply architectures of OAM-form-factor AI processors, PCIe acceleration cards, and HPC platforms.

In these scenarios, the MPC22168-170 typically works in conjunction with a three-state PWM controller. By paralleling multiple modules, the system-level current output is further expanded to cover various power levels, ranging from single-phase high-current applications to multi-phase arrays.
