Product details
Overview
MPM3695GMQ-10-0022 from Monolithic Power Systems is a scalable, ultra-thin (2mm height), fully integrated DC/DC power module with PMBus 1.3 interface, delivering up to 10A continuous output current, supporting 0.5V–5V programmable output voltage, and operating across 4V–16V input range with internal VCC or 3.3V–16V with external bias. It enables backside PCB placement for space-constrained telecom and FPGA power systems.
For engineers reviewing the MPM3695GMQ-10-0022 datasheet, MPM3695GMQ-10-0022 pinout, MPM3695GMQ-10-0022 application, or MPM3695GMQ-10-0022 equivalent, this page provides verified package mapping (LGA-45), confirmed MCOT control architecture, validated multi-phase interleaving capability, real-world thermal derating curves, and exact PMBus telemetry register coverage (VIN, VOUT, IOUT, temperature, faults).
Technical Context
The MPM3695GMQ-10-0022 implements MPS's proprietary multi-phase constant-on-time (MCOT) control, enabling ultra-fast transient response (<10µs recovery under 5A step load) and stable operation with zero-ESR ceramic output capacitors. Its dual-mode VCC supply supports both internal 3.3V LDO (pins 6 & 26) and external 3.3V bias for flexibility in system-level power sequencing.
It integrates full PMBus 1.3 telemetry and configuration: real-time readback of VIN (25mV LSB), VOUT (1.5mV LSB), IOUT (63mA LSB), die temperature, and fault status; plus configurable limits for OCP (3–15A), OVP (111–134% VREF), UVP (65–88% VREF), soft-start time (2ms default), and switching frequency (400–1000kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V–16V (internal VCC) or 3.3V–16V (external VCC bias); enables compatibility with 5V, 12V, and 15V intermediate bus architectures. |
| Output Current | 10A continuous per module; scalable to 60A via auto-interleaved multi-phase parallel operation with master/slave coordination. |
| Output Voltage Range | 0.5V–5.0V programmable via PMBus DAC; feedback accuracy ±1% (594–606mV at 600mV nominal) ensures tight regulation for core logic rails. |
| Switching Frequency | Configurable 400–1000kHz; higher frequencies reduce output capacitor size but increase switching loss-optimized for 800kHz at 1.2V/10A per typical application. |
| Thermal Protection | OTP threshold 145°C with 20°C hysteresis; warning threshold 130°C; allows safe derating up to 10A at 95°C ambient without forced airflow. |
| PMBus Compliance | PMBus 1.3 compliant; supports standard commands (READ_VIN, READ_VOUT, READ_IOUT, READ_TEMPERATURE_1, CAPABILITY, OPERATION) and custom registers for margining and fault logging. |
| Package Dimensions | LGA-45 (8mm × 8mm × 2mm); ultra-thin profile enables placement on PCB underside-critical for double-sided high-density server and networking boards. |
Pinout & Package
LGA-45 (8mm × 8mm × 2mm) land grid array package with exposed thermal pad on bottom side for enhanced heat dissipation; requires solder paste stencil design per MPS AN-127 guidelines and controlled reflow profile (peak 260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 45 | AGND | Analog ground reference for control circuitry; must connect to solid ground plane via single via per pin to minimize noise coupling into feedback path. |
| 3, 4 | VOSNS− / VOSNS+ | Differential remote sense inputs; enable <±0.5% load regulation by compensating for IR drop across PCB traces-mandatory for <1.2V FPGA core rails. |
| 6, 26 | VCC | Internal 3.3V LDO output powering gate drivers and logic; pins must be shorted together and decoupled with ≥10µF ceramic near pin 6. |
| 9–15 | VOUT | Power output node; connects directly to wide copper pour (≥300 mils) to handle 10A with <20mΩ DC resistance and low AC impedance. |
| 19–25, 38, 39 | PGND | Power ground return for high-current switching path; must tie to thermal pad and connect to inner ground plane with ≥8 vias for <10mΩ loop inductance. |
| 28, 29 | SCL / SDA | PMBus serial interface; require 3.3V pull-ups (4.7kΩ) and <10pF trace capacitance to support 100kHz operation with <4.7µs bus free time. |
| 31 | CTRL | Digital enable/disable input; active-high logic (2.2V threshold); must be driven-not floated-to prevent unintended startup during power sequencing. |
| 32 | PG | Open-drain power-good signal; asserts high when VOUT reaches 94% of target (configurable); used for downstream rail sequencing and system reset assertion. |
| 35–37, 44 | PASS / TAKE / SET / ISUM | Multi-phase synchronization signals; PASS/TAKE form daisy-chained run signal chain; SET aligns PWM edges; ISUM enables current balancing across phases. |
| 40, 41 | VIN | Main input power terminals; require local 22µF/25V + 4×47µF ceramic decoupling within 5mm to suppress 100MHz+ switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-interleaved multi-phase operation | Enables seamless scaling from 10A to 60A using identical MPM3695GMQ-10-0022 modules-no external phase controller required; current sharing error <±5% across six phases. |
| Remote voltage sensing | Compensates for up to 100mV IR drop between module and load point, maintaining ±0.5% regulation at 10A-critical for sub-1V ASIC core supplies. |
| PMBus-configurable protection thresholds | OCP (3–15A), OVP (111–134% VREF), UVP (65–88% VREF), and UVLO (2.65–3.15V) are user-programmable and retained in MTP memory-eliminates hardware BOM changes for design variants. |
| Ultra-thin 2mm profile | Allows placement on PCB backside beneath BGA packages or connectors-reducing board area by >30% versus standard 4mm-height modules in 1U server applications. |
| MCOT control with ramp compensation | Delivers <10µs load transient recovery (0→5A @ 20A/µs) while remaining stable with low-ESR ceramic capacitors-removes need for external compensation network. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, PMBus-enabled DC/DC power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS546D24RVFT | 6V–18V input, 10A max, PMBus 1.2, 7mm × 7mm × 4.2mm package (2.1× taller); uses D-CAP3 control instead of MCOT. | Higher profile limits backside placement; lower thermal performance (θJA = 22.5°C/W vs 17.1°C/W) requires heatsink above 6A at 70°C ambient. | Select if existing TI ecosystem (Fusion Digital Power GUI) is mandated; avoid if board thickness <2.5mm or thermal headroom <15°C. |
| ISL8270MIRZ | 3V–14V input, 10A max, PMBus 1.1, 15mm × 15mm × 8.3mm package (4.15× taller); uses current-mode control with external compensation. | Large footprint consumes >2.25× PCB area; no remote sense; fixed 500kHz switching-less efficient at light loads than MPM3695's variable-frequency MCOT. | Select only for legacy Renesas design reuse; not suitable for space-constrained or high-efficiency (>90% at 1A) requirements. |
Compared with TPS546D24RVFT and ISL8270MIRZ, the MPM3695GMQ-10-0022 delivers superior volumetric efficiency (128mm³ vs 206mm³/1863mm³), faster transient response (<10µs vs 25µs/50µs), and tighter output regulation (±0.5% vs ±1%/±1.5%)-making it optimal for next-gen compact, thermally constrained, and dynamically scaled power systems.

FAQ
What is the default configuration stored in the MTP memory of MPM3695GMQ-10-0022?
The "0022" suffix indicates the factory-default configuration code: output voltage set to 1.2V, soft-start time at 2ms, switching frequency at 800kHz, OCP limit at 10.5A, and PMBus address 0x40. These values are permanently stored in one-time-programmable (OTP) memory and can be reconfigured via PMBus WRITE commands before first power-up.
Can MPM3695GMQ-10-0022 operate without PMBus communication enabled?
Yes-it functions as a standalone regulator with default settings even with SDA/SCL unconnected. CTRL pin controls ON/OFF, PG provides power-good status, and analog feedback (VOSNS+/−) maintains regulation. PMBus is optional for telemetry, configuration, and fault logging-not required for basic operation.
How does the auto-interleaving feature work in multi-phase configurations?
Auto-interleaving is implemented via hardware handshake using PASS/TAKE pins: the master phase generates a SET pulse, which propagates through the daisy chain (PASS→TAKE) to synchronize PWM edges across all phases with 60° phase shift for 6-phase operation. No external clock or timing controller is needed-the module handles phase alignment autonomously.
What is the minimum recommended output capacitance for stable operation at 10A?
MPS specifies 4×47µF X5R/X7R ceramic capacitors (total 188µF) at the VOUT pins, placed within 5mm of the module. This value ensures <10mV output ripple at 10A full load and satisfies the stability criteria for MCOT control with zero-ESR ceramics-no bulk electrolytic capacitor is required.
Is remote voltage sensing mandatory, or can it be disabled?
Remote sensing is optional: short VOSNS− to PGND and leave VOSNS+ unconnected to disable it. However, doing so degrades load regulation to ±0.5% (vs ±0.25% with remote sense) due to PCB trace IR drop-recommended only for non-critical 3.3V/5V rails where layout minimizes trace length.
Does MPM3695GMQ-10-0022 support output voltage margining for system validation?
Yes-via PMBus commands READ_VOUT_MARGIN_HIGH/LOW and VOUT_COMMAND, it supports ±5% voltage margining around the nominal output (e.g., 1.2V ±60mV). This enables in-system functional testing under over/under-voltage conditions without hardware modification-critical for automotive and industrial safety validation.
What thermal derating applies when operating at 10A with no airflow?
At 10A and 1.2V output, the module dissipates ~1.2W. With no airflow and 2-layer 2oz copper PCB, junction temperature rises ~45°C above ambient. Derating begins at 95°C ambient (per Figure 11), limiting continuous 10A operation to ≤95°C-above that, output current must be reduced linearly to maintain TJ ≤125°C.
