Power Density Challenges in AI Computing Power Supply
As the power consumption of AI servers and GPU accelerator cards continues to rise, core processors are placing unprecedented demands on the current output capacity and power density of power supply modules. According to forecasts by QunZhi Consulting, global AI server shipments are expected to reach approximately 3.7 million units in 2026, representing a year-over-year increase of 51.3%. Meanwhile, the TDP of flagship AI chips such as NVIDIA’s B200 and GB200 has already exceeded 1,000 W. Amid this trend, traditional discrete DrMOS solutions are gradually reaching their limits in terms of current capacity, switching noise, and PCB footprint, while highly integrated, low-EMI monolithic half-bridge solutions have emerged as the key path for upgrading server power supply architectures.
The MP87297, introduced by MPS (Monolithic Power Systems), is a next-generation Intelli-Phase™ DrMOS product specifically designed to address this need. This device integrates a power MOSFET, gate driver, and current/temperature sensing capabilities onto a single chip, delivering up to 100A of continuous output current in a 4mm × 6mm TLGA-34 package. It is specifically designed for server applications that demand high efficiency and a compact form factor.
Product Overview
The MP87297 is a monolithic half-bridge Intelli-Phase™ DrMOS solution with an integrated power MOSFET and gate driver. It delivers a continuous output current (IOUT) of up to 100 A across a wide input voltage range and operates at frequencies from 100 kHz to 1.5 MHz. The device utilizes MPS’s proprietary Quiet Switcher™ technology (QST™), which suppresses voltage ringing through a unique circuit design and monolithic architecture. This effectively limits peak switching voltages, improves device reliability, reduces electromagnetic interference, and minimizes sensitivity to PCB layout.
The MP87297 can be used in conjunction with a three-state pulse-width modulation (PWM) signal controller (such as the MP2985B). It also integrates Accu-Sense™ current sensing to monitor inductor current (IL) and temperature sensing to report junction temperature (TJ), providing precise telemetry data for system-level power management.

MP87297 Key Technical Features
Quiet Switcher™ Technology (QST™). The MP87297’s core technological differentiation lies in its patented Quiet Switcher™ technology. This technology utilizes a circuit design unique to the monolithic architecture to suppress voltage ringing and limit peak switching voltages, thereby reducing EMI emissions while enhancing the device’s long-term reliability. Since ringing suppression does not rely on external buffer circuits or complex PCB layout compensation, this technology significantly reduces layout sensitivity in power supply designs, helping to shorten the development cycle of server power modules.
Accu-Sense™ Dual Current and Temperature Sampling. The MP87297 integrates high-precision current sampling capabilities to monitor inductor current in real time; it also incorporates temperature sampling to report the chip’s junction temperature to the controller. This dual-sampling mechanism provides precise current sharing data and thermal management information for multi-phase server power supply systems, helping to optimize system efficiency and dynamic response.
Three-State PWM Compatibility. The device supports three-state pulse-width modulation (PWM) signal inputs and can be flexibly paired with multi-phase controllers such as the MPS MP2985B to implement multi-phase parallel power supply architectures. In server CPU/GPU core power supplies, multiple MP87297 devices can be connected in parallel to form a multi-phase buck converter, meeting core current demands in the hundreds of amperes.
Comprehensive Protection and Fault Reporting. The MP87297 features built-in current-limit protection and over-temperature protection, and supports a fault reporting mechanism that notifies the controller of fault conditions under abnormal operating conditions, ensuring the safe operation of server power supply systems.
MP87297 Typical Application Scenarios
Server CPU/GPU Core Power Supply. The MP87297’s primary application is providing core voltage for server processors and AI accelerator chips. Its 100A per-module output capability and multi-phase parallel scaling features enable it to meet the power supply requirements ranging from general-purpose server CPUs to high-power AI GPUs. The MP87297 is ideally suited for server applications requiring high efficiency and a compact form factor, enabling high-power-density power supply designs within limited board space.
Multi-Phase Buck Converter Architecture. In the multi-phase power supply architecture of server motherboards, multiple MP87297 devices can be combined with three-state PWM controllers such as the MP2985B to form 2-phase, 4-phase, or even higher-phase-count buck converters. Take the two-phase evaluation board EVL87297-2PHASE-00A as an example: this board can deliver up to 200 A of continuous load current, fully demonstrating the MP87297’s power delivery capabilities in multi-phase parallel configurations.
AI Server Power Systems. As power consumption in AI servers rises sharply, DrMOS—as the core power device in server VRMs—is experiencing market opportunities characterized by growth in both volume and price. With its high integration, low EMI, and precise telemetry capabilities, the MP87297 provides a highly reliable power stage solution for AI server power systems.
