Product details
Overview
MPM82504GBH-0016 from Monolithic Power Systems is a quad-output, scalable DC/DC power module with PMBus interface, delivering up to 25A per channel across four independent outputs. It supports parallel configurations (50A/75A/100A), operates from 3.2V–16V input, regulates output from 0.5V–3.3V, and uses multi-phase constant-on-time (MCOT) control for ultra-fast transient response. It is deployed in high-density FPGA core power systems requiring precise digital telemetry and dynamic reconfiguration.
For engineers reviewing the MPM82504GBH-0016 datasheet, MPM82504GBH-0016 pinout, MPM82504GBH-0016 application, or MPM82504GBH-0016 equivalent, this page delivers verified package mapping (BGA-253L), confirmed PMBus 1.3 compliance, validated four-channel remote sensing architecture, and real-world efficiency curves at 12V input across 0.5V–3.3V VOUT.
Technical Context
The MPM82504GBH-0016 implements MPS's proprietary multi-phase constant-on-time (MCOT) control architecture, enabling stable regulation with minimal external compensation and sub-100ns load-step response. Its four independent buck channels integrate power MOSFETs, drivers, inductors, and thermal sensors in a single BGA package.
Digital configuration and monitoring are enabled via a full PMBus 1.3 interface supporting telemetry readback of VIN, VOUT, IOUT, temperature, and fault status per channel - with programmable OCP, OVP, UVP, OTP thresholds, soft-start time, switching frequency, and PWM mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.2V–16V (with external 3.3V VCC bias) or 4V–16V (with internal VCC bias) - enables compatibility with 5V, 12V, and 15V intermediate bus architectures |
| Output Current per Channel | Up to 25A continuous - supports high-current ASIC/FPGA core rails without external current sharing circuitry |
| Output Voltage Range | 0.5V–3.3V - covers DDR memory, CPU cores, and SoC I/O domains with ±0.5% DC load/line regulation |
| Switching Frequency | 600kHz–1000kHz (configurable per channel) - balances efficiency and component size for high-density PCB layouts |
| PMBus Compliance | PMBus 1.3 - provides standardized commands for voltage margining, fault logging, and real-time telemetry across all four channels |
| Thermal Protection | OTP threshold at 150°C (rising), 125°C (falling); warning at 125°C/100°C - ensures safe operation under sustained overload or airflow loss |
| Package | BGA-253L (15mm × 30mm × 5.18mm) - thermally optimized for bottom-side cooling and high-current PCB copper planes |
Pinout & Package
BGA-253L package (15mm × 30mm × 5.18mm) with exposed thermal pad; requires controlled-depth solder paste and 6-layer PCB with dedicated ground/power planes for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1–VIN4 | Input supply for channels 1–4 | Each accepts 3.2V–16V; decoupling capacitors must be placed within 3mm of each VIN–GND pair |
| VOUT1–VOUT4 | Regulated output nodes | Direct connection to load; each supports up to 25A with integrated inductor and synchronous rectification |
| VOSNS1+–VOSNS4+ | Remote sense positive inputs | Connect directly to load VOUT point to compensate for IR drop in PCB traces |
| VOSNS1−–VOSNS4− | Remote sense negative returns | Connect to local GND sense point at load; short to GND if remote sensing is unused |
| CTRL1–CTRL4 | Enable/disable digital inputs | Active-high logic; must be driven (not floated); tied together in parallel configurations |
| PG1–PG4 | Open-drain power-good indicators | Assert high when VOUT reaches ≥90% of nominal; require external 10kΩ pull-up to 3.3V |
| SCL/SDA/ALT | PMBus interface signals | Support 10kHz–1MHz clock; ALT is active-low interrupt for fault conditions |
| ADDR1–ADDR4 | PMBus address configuration | Set unique per-channel addresses using resistor-to-GND; identical addresses required for parallel operation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-interleaving support | Enables seamless multi-phase operation across channels or multiple modules, reducing input/output ripple by up to 70% |
| Individual remote sense per channel | Compensates for up to 50mV IR drop between module and load, maintaining ±0.5% output accuracy under full load |
| Configurable over-current protection | Valley current limit adjustable from 1.5A to 27A per channel via PMBus register D7h |
| Non-volatile memory (NVM) | Stores default configuration (e.g., -0016 code) including VOUT, soft-start, OVP/UVP thresholds, eliminating boot-time initialization |
| Thermal derating without forced air | Full 100A capability maintained up to 60°C ambient on 6-layer evaluation board; linear derating above that point |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-output, digitally configurable power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPM3695-100 | Single-channel 100A module; no native quad-channel integration; requires external current-sharing circuitry for multi-rail use | Best suited for single-rail, ultra-high-current applications (e.g., GPU VRMs); lacks per-channel telemetry and remote sense | Select when needing >100A on one rail rather than four independent rails |
| TPS546D24A | Single-channel 60A DCAP-based controller (requires external MOSFETs, inductors, and PMBus transceiver); smaller footprint but higher design complexity | Used in space-constrained, cost-sensitive telecom line cards where layout flexibility outweighs integration benefits | Select when board-level customization, thermal partitioning, or mixed-vendor component sourcing is required |
Compared with MPM82504GBH-0016, the MPM3695-100 trades channel independence for raw current capacity, while the TPS546D24A shifts integration burden to the designer - making the MPM82504GBH-0016 optimal for rapid deployment of multi-rail, telemetry-rich systems.

FAQ
What input voltage ranges does the MPM82504GBH-0016 support, and how does VCC bias affect operation?
The device supports 3.2V–16V input with external 3.3V VCC bias, or 4V–16V with internal VCC generation. External bias enables higher efficiency at low VIN but disables MTP programming; internal bias allows full PMBus configurability across the full 4V–16V range.
How is current sharing ensured when paralleling multiple MPM82504GBH-0016 modules?
Auto-interleaving synchronizes switching phases across channels/modules, while matched VOSNS+ and VOSNS− connections enforce voltage-mode current sharing. PMBus-configurable current limits and phase-shedding pins (PS1–PS4) further optimize load distribution under dynamic conditions.
Can the MPM82504GBH-0016 operate with only two channels active while the others remain powered down?
Yes - CTRL1–CTRL4 independently enable/disable each channel. Unused channels can be disabled via PMBus or hardwired CTRLx = low; ISUMx, PASSx, and TAKEx pins must be floated or terminated per datasheet Table 4 guidance to prevent unintended interaction.
What thermal management requirements apply to the BGA-253L package?
The module requires a 6-layer PCB with internal ground/power planes and ≥4 thermal vias under the exposed pad. On the EVM82504-BH-00A board, θJA is 5.77°C/W; derating begins above 60°C ambient without forced air, reaching 50% rated current at 100°C.
Does the PMBus interface support write-protection of configuration registers?
Yes - the MPM82504GBH-0016 includes hardware write-protection via the PMBus STORE_DEFAULT_ALL command and software lock bits (register D0h). Once locked, configuration changes require explicit unlock sequence, preventing accidental modification during system operation.
How does the MCOT control architecture improve transient response compared to traditional voltage-mode controllers?
MCOT eliminates loop compensation components by directly sensing on-time based on output voltage error, achieving <100ns load-step response with inherent stability across ceramic capacitor output networks - unlike voltage-mode designs requiring careful ESR/ESL tuning.
Is the -0016 configuration code pre-programmed in non-volatile memory, and what does it define?
Yes - the -0016 suffix indicates factory-programmed NVM settings including default VOUT values, soft-start time (2ms), OVP/UVP thresholds, and PMBus address mapping. These persist through power cycles and eliminate host-initiated configuration overhead at startup.
