Mingjiada Electronics provides a long-term, stable supply of the MPS (Monolithic Power Systems) MPM82504 and offers high-price buyback services for this product worldwide. This device is a four-channel, 25A, scalable, fully integrated DC/DC power module with a PMBus interface, housed in a BGA (15mm × 30mm × 5.18mm) package. It provides a complete, high-power-density, and highly flexible power solution for applications such as servers, FPGA/ASIC core power supplies, and telecommunications and networking systems.

Product Overview

The MPM82504 is a four-channel, 25A, scalable, fully integrated power module with a PMBus interface. This device provides a complete power solution, with each output channel capable of delivering up to 25A. The MPM82504 features four parallel-capable output channels that can be flexibly configured to provide 50A, 75A, or 100A of output current. The device can also be paralleled with the MPM3695-100 and other MPM82504 devices to provide higher output currents, scalable up to 800A.

The device utilizes MPS’s proprietary Multi-Phase Constant On-Time (MCOT) control technology, which provides ultra-fast transient response and simple loop compensation. The PMBus interface enables flexible digital configuration and monitoring of key parameters, while comprehensive protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and over-temperature protection (OTP). The MPM82504 requires only a minimal number of readily available external components.

Key Features

Four Parallel-Capable Output Channels with Flexible Configuration: The MPM82504 features four parallel-capable output channels, each capable of delivering up to 25A. Users can flexibly configure the device to provide four independent 25A outputs, two 50A outputs, or a single 100A output by paralleling the channels. By paralleling multiple modules, the output current can be further scaled up to 800A, meeting a wide range of power requirements from small and medium to ultra-high power applications.

MCOT Multi-Phase Constant On-Time Control: Utilizing MPS’s proprietary MCOT control technology, it provides ultra-fast transient response with minimal required output capacitance while enabling simple loop compensation. The four-phase design, combined with automatic interleaving, effectively reduces input and output ripple.

PMBus 1.3 Digital Interface: The PMBus interface enables flexible digital configuration and monitoring of key parameters. Each channel can be configured via PMBus to set parameters such as output voltage, soft-start time, overcurrent/over-temperature/overvoltage/undervoltage and UVLO thresholds, PWM mode, and switching frequency.

Comprehensive Telemetry Readback: Supports real-time telemetry readback of VIN, VOUT, IOUT, temperature, and fault information for each channel, facilitating precise power management and fault diagnosis within the system.

Independent Remote Sensing: Each output channel features independent remote sensing to compensate for PCB trace voltage drops and ensure load-side voltage accuracy.

Comprehensive Protection Features: Integrated overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and overtemperature protection (OTP) ensure safe system operation under various abnormal conditions.

Minimal External Components: The module is highly integrated, requiring only a minimal number of readily available external components to complete the design, which significantly simplifies the power supply solution and reduces PCB footprint.

Typical Application Scenarios

The MPM82504 is primarily designed for the following high-power-density power supply scenarios:

Servers and Computing Equipment: Provides high-power-density, scalable power supply solutions for server CPUs, GPUs, and accelerator cards, making it an ideal choice for data center power architectures.

FPGA and ASIC Core Power Supplies: Meets the high-current and fast transient response power supply requirements of field-programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs). When used with module solution reference designs such as the NXP LX2160A/LS2081A, it is suitable for data center applications.

Telecommunications and Networking Systems: Provides efficient and reliable power supply for 5G base stations, communications equipment, and network switching systems.

Industrial Equipment: Suitable for applications requiring power supply reliability and flexibility, such as industrial automation and test and measurement systems.
