Product details
Overview
MPM3683GMN-10-T from Monolithic Power Systems is a fully integrated 10A DC/DC step-down power module with 2.7V–16V input range, 0.6V–5.5V adjustable output, and adaptive constant-on-time (COT) control. It integrates power MOSFETs, inductor, and passive components in an FCM LGA-29 (7mm×7mm×4.4mm) package, delivering high efficiency in telecom base stations and FPGA power rails.
For engineers reviewing the MPM3683GMN-10-T datasheet, MPM3683GMN-10-T pinout, MPM3683GMN-10-T application, or MPM3683GMN-10-T equivalent, key selection criteria include configurable switching frequency (600/800/1000 kHz), differential remote sense capability, pre-biased start-up support, and non-latched OCP/OVP/OTP protections.
Technical Context
The MPM3683GMN-10-T implements adaptive COT control with internal ramp compensation to ensure stability across full VIN (4V–16V) and VOUT (0.6V–5.5V) ranges using zero-ESR ceramic output capacitors. Its valley-current sensing architecture enables cycle-by-cycle over-current protection via external RCS resistor configuration.
It supports dual operating modes-forced continuous conduction mode (FCCM) and pulse-skip mode (PSM)-selected via MODE pin resistor network, with fixed on-time determined by VIN, VOUT, and selected fSW. The TRK/REF pin enables precise voltage tracking or external reference injection, while PG provides open-drain power-good signaling with 92.5%–101% VREF thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V–16V (internal bias) or 2.7V–16V (external 3.3V bias): Enables direct use from 5V/12V rails or wide-input industrial supplies. |
| Output Current | 10A continuous: Sustains full load without derating at 25°C ambient on 4-layer EVM with airflow. |
| Output Voltage Range | 0.6V–5.5V: Supports core voltages for modern FPGAs (0.8V), ASICs (1.2V), and I/O rails (3.3V/5V). |
| Switching Frequency | 600/800/1000 kHz (pin-selectable): Balances efficiency, size, and EMI; remains constant regardless of VIN or VOUT. |
| Feedback Reference | 600 mV ±1% (–40°C to +125°C): Enables accurate regulation with tight tolerance across temperature. |
| Thermal Shutdown | 160°C with 30°C hysteresis: Prevents permanent damage during sustained overload or poor heatsinking. |
| Power Good Threshold | 92.5%–101% VREF rising/falling: Ensures reliable system sequencing and fault detection before downstream logic powers up. |
Pinout & Package
The MPM3683GMN-10-T is housed in a compact FCM LGA-29 package (7mm × 7mm × 4.4mm) with exposed thermal pad on underside for PCB-level heat dissipation. Pin layout follows standardized top-view orientation with dedicated AGND, PGND, and RGND pins for optimal noise isolation and remote sensing accuracy.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6, 7 | VOUT | Primary output node; connects directly to bulk and ceramic output capacitors; requires low-inductance routing to minimize ripple. |
| 3 | EN | Digital enable input; 1.22V threshold with 200mV hysteresis; must be pulled high via resistor for automatic startup-never left floating. |
| 4 | PG | Open-drain power-good signal; requires external pull-up; asserts high when VOUT is within ±7.5% of target, enabling safe system boot. |
| 5, 8, 9, 27, 28 | VIN | Main input power terminals; multiple pins reduce IR drop and improve current sharing; connect to low-ESR input capacitors near package edge. |
| 10, 11, 12 | PGND | Power ground return for VOUT path; must be tied to thermal pad and routed separately from AGND to avoid noise coupling into feedback loop. |
| 13 | VCC | Internally regulated 3V LDO output; powers control circuitry; includes integrated 1μF capacitor-no external bypass required. |
| 14, 15, 16, 19, 20, 29 | SW | Switch node connecting internal HS/LS MOSFETs to inductor; demands large copper pour for thermal management and EMI reduction. |
| 22 | CS | Current-sense input; connects to AGND via external RCS resistor to set valley-current OCP threshold (e.g., 16kΩ for 10A limit). |
| 23 | MODE | Configurable mode select; resistor-to-GND or VCC sets FCCM/PSM and fSW (600/800/1000 kHz) per Table 1 in datasheet. |
| 24 | TRK/REF | Tracking/reference input; accepts 0.3V–1.4V analog signal to force VOUT tracking; also sets soft-start time via external capacitor. |
| 25 | RGND | Remote sense negative input; connects directly to load-side ground point to compensate for PCB trace IR drop in high-current applications. |
| 26 | FB | Differential remote sense positive input; forms voltage divider with RGND to set VOUT; must be placed adjacent to IC for minimal noise pickup. |
Key Features
| Feature | Design Value |
|---|---|
| Differential Remote Sense | Separate RGND and FB pins enable millivolt-level output regulation accuracy under high-current PCB trace voltage drops. |
| Pre-Biased Start-Up | Monotonic startup into pre-charged outputs prevents reverse current flow and ensures deterministic power sequencing in multi-rail systems. |
| VOUT Discharge | Integrated 80Ω discharge MOSFET actively pulls VOUT to ground when EN is deasserted, eliminating hold-up time and supporting hot-swap compliance. |
| Adaptive COT Control | Internal ramp compensation eliminates need for external compensation network and guarantees stability with MLCC-only output filters. |
| Configurable Soft-Start | TRK/REF pin accepts external capacitor to scale soft-start time beyond default 1.6ms (e.g., 100nF → 1.6ms; 1µF → ~16ms), reducing inrush stress. |

FAQ
What is the minimum recommended input voltage for reliable operation?
The MPM3683GMN-10-T operates reliably from 4V when using internal bias, or down to 2.7V with an external 3.3V bias applied to VCC. Below 4V, internal LDO cannot sustain control circuitry without external support-verified per Recommended Operating Conditions table (p.5). Input undervoltage lockout triggers at 2.4V rising threshold.
How does the MODE pin configure switching frequency and light-load mode?
The MODE pin selects both fSW and conduction mode via resistor value: GND = PSM@600kHz; 34.8kΩ to GND = FCCM@600kHz; 243kΩ to GND = PSM@800kHz; 80.6kΩ to GND = FCCM@800kHz; open = PSM@1000kHz. Configuration is validated in Table 1 (p.15) and confirmed by electrical characterization at TJ = 25°C.
Can the MPM3683GMN-10-T safely start into a pre-biased output?
Yes-it features monotonic pre-biased start-up. When VOUT is pre-charged, the IC disables switching until TRK/REF exceeds sensed FB voltage; LS-FET pulses briefly to charge BST without discharging VOUT. This behavior is documented in the Operation section (p.16) and verified on EVM3683-10-MN-01A.
What is the purpose of the RGND pin and how should it be connected?
RGND is the dedicated remote sense ground reference for differential feedback. It must be connected directly to the load-side ground point-not to PGND-to cancel voltage drop across PCB traces. If remote sensing is unused, RGND must be shorted to PGND per Pin Functions table (p.4); failure to do so causes regulation error.
How is over-current protection configured and what is its response behavior?
OCP is set by external RCS resistor on CS pin, targeting valley inductor current (e.g., 16kΩ yields ~10A limit). Upon fault, hiccup mode activates after 31 consecutive cycles, latching off HS/LS-FETs for ~11ms before auto-retry. This non-latched protection is specified in Electrical Characteristics (p.6) and validated in SCP test waveforms (p.11–12).
Is an external bootstrap capacitor required on the BST pin?
No-BST capacitor is fully integrated internally. The datasheet explicitly states "BST capacitor (CBST) is integrated internally, and does not require an external connection" (p.4, Pin Functions). Adding external capacitance may disrupt internal charge pump timing and is not supported.
What thermal performance can be expected in a standard 4-layer PCB layout?
On the EVM3683-10-MN-01A (64mm×64mm, 4-layer), θJA is 16.2°C/W and θJC is 5.1°C/W. At 10A/12V input, case temperature rise is ~45°C (p.9), enabling full-rated output without forced airflow. Derating begins above 65°C ambient per Thermal Derating curve (p.9).
