Product details
Overview
MPM54313GBJ-0000-T from Monolithic Power Systems is a triple-output, fully integrated 3A power module with I²C interface, adaptive constant-on-time (COT) control, and built-in sequencing logic. It delivers three independent 0.4V–5.5V outputs (each up to 3A), supports parallel operation (up to 6A dual-phase or 9A three-phase), and provides real-time monitoring of VOUT, IOUT, and junction temperature - deployed in FPGA/ASIC core voltage regulation where tight transient response and coordinated rail startup are critical.
For engineers reviewing the MPM54313GBJ-0000-T datasheet, MPM54313GBJ-0000-T pinout, MPM54313GBJ-0000-T application, or MPM54313GBJ-0000-T equivalent, key selection criteria include configurable soft-start timing (2ms per channel), ±1.5% output voltage accuracy across temperature, differential remote sensing per buck, and I²C-addressable configuration of UVLO/OVP thresholds, switching frequency (500–1000kHz), and active voltage positioning (AVP) for passive current sharing.
Technical Context
The MPM54313GBJ-0000-T integrates three synchronous buck regulators with monolithic inductors, adaptive COT control architecture, and a dedicated I²C master interface supporting up to nine slave addresses via ADDR1/ADDR2 pins. Each buck features independent feedback loops with differential remote sense (VSA+/VSA−, VSB+/VSB−, VSC+/VSC−), programmable soft-start (2ms default), and configurable power-on/off sequencing stored in MTP memory or updated dynamically via I²C.
It implements full protection including over-current (3.6A valley limit), over-voltage (112% VREF latch-off), under-voltage (85% rising / 80% falling), thermal shutdown (145°C), and input over-voltage lockout (15V). The device supports pre-biased start-up, PFM/PWM mode selection, and active current balancing in interleaved dual-phase mode (buck A+B) or passive balancing in three-phase parallel mode using AVP droop.

Pinout & Package
MPM54313GBJ-0000-T uses an 8mm × 9mm × 2.58mm BGA package with 64 solder balls, optimized for high-density PCB layouts and thermal performance via bottom-side GND and thermal pad connection. Pin assignment follows standard MPS BGA layout with dedicated VIN, GND, VCC, AGND, PG, SCL/SDA, EN, ADDR1/ADDR2, and three independent buck output/feedback/switching nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–C2, A4–C5, A7–C8 | VOA / VOB / VOC | Three independent buck output terminals - each rated for 3A continuous; support parallel operation with external current-sharing resistors or AVP. |
| D4/E4, D5/E5, D6/E6 | VAS+/VAS−, VBS+/VBS−, VCS+/VCS− | Differential remote sense inputs - Kelvin-connected to output capacitors to reject PCB IR drop and maintain ±1.5% regulation accuracy. |
| J7/K7, J4/J5 | SDA/SCL, ADDR2/ADDR1 | I²C data/clock and address configuration pins - enable nine unique I²C addresses; support dynamic reconfiguration during operation. |
| K4, E3, K5 | EN, PG, VCC | Enable control (1.2V logic high), open-drain power-good status indicator, and internal 3.3V LDO output for biasing analog circuitry. |
| F1–F9, G1–G9, H1–H9, J1–J9, K1–K9 (excluding signal pins) | GND / VIN / AGND / BSTx / SWx / TPx | Power ground (32 pins), input supply (12 pins), analog ground (2 pins), bootstrap (3), switching node (3), and test points (4) - ensure low-impedance return paths and thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Triple 3A integrated buck with monolithic inductors | Eliminates 18 external inductors and reduces solution footprint by >40% versus discrete controllers + external magnetics. |
| Configurable power-on/off sequencing (MTP or I²C) | Enables precise startup/shutdown order across three rails - critical for FPGA I/O/core voltage ramp requirements and system-level reliability. |
| Active voltage positioning (AVP) and interleaving support | AVP generates controlled droop for passive current sharing in 3-phase parallel; interleaving enables active balancing and 50% ripple reduction in dual-phase mode. |
| Real-time telemetry via I²C (VOUT, IOUT, TJ) | On-chip ADC provides 220 LSB (3.3V) and 24 LSB (3A) resolution - enables closed-loop thermal management and dynamic load-line adjustment. |
| Pre-biased start-up and PFM/PWM mode selection | Guarantees monotonic rise into pre-charged loads; PFM extends light-load efficiency while PWM maintains fixed frequency for EMI control. |
Applications
| FPGA Core Voltage Regulation | Optical Transceiver Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPM54303GBJ-0000-T | Triple 2A output; no I²C telemetry (VOUT/IOUT/TJ readback); fixed 600kHz fSW; no AVP or interleaving. | Lacks real-time monitoring and advanced current-sharing modes - suitable only for static, non-critical rail sequencing. | Select when cost sensitivity outweighs telemetry needs and load currents remain ≤2A per rail. |
| TPS54JB20RQF | Triple 3A module with PMBus interface; includes VR14.0 compliance, SVID support, and enhanced fault logging. | Targeted at server CPU VR applications; requires VR14-compliant controller and complex firmware integration. | Choose for x86 server platforms needing SVID handshake and VR14.0 compliance - not drop-in compatible with MPM54313's I²C register map. |
Compared with MPM54303GBJ-0000-T, the MPM54313GBJ-0000-T adds telemetry, AVP, and interleaving for dynamic current management; versus TPS54JB20RQF, it offers simpler I²C integration and broader input range but lacks SVID/VR14.0 protocol support.

FAQ
What is the default I²C slave address for MPM54313GBJ-0000-T?
The default I²C slave address is 0x60, set when ADDR1 and ADDR2 are both pulled low. Nine unique addresses (0x60–0x68) are available by configuring ADDR1/ADDR2 as high, low, or floating - verified in the Electrical Characteristics table (page 5) and confirmed in register map section 0x00h.
Can buck A and buck B be operated in interleaved mode while buck C runs independently?
Yes - the MPM54313GBJ-0000-T supports dual-phase interleaving between buck A and buck B (enabling 6A total with active current balancing), while buck C operates independently at its own voltage and timing. This is enabled via DUAL_PHASE_EN bit in the control register and requires VSA+ tied to VSB+.
Does the device support output discharge during shutdown?
Yes - output discharge is configurable via DISCHARGE_R_REG (0Eh). When enabled, an internal resistor (10Ω or 2Ω selectable) discharges the output capacitor after shutdown, preventing residual voltage that could interfere with downstream logic or cause inrush on restart.
What is the maximum allowed input voltage for continuous operation?
The recommended operating input voltage is 4V to 16V. The absolute maximum rating is 18V (per Absolute Maximum Ratings table, page 6), but sustained operation above 16V risks exceeding thermal limits and violating UVLO hysteresis margins - confirmed in Recommended Operating Conditions.
How is junction temperature measured and reported via I²C?
Junction temperature is measured by an on-die thermal sensor and reported as a 10-bit value (0–1023) via register 0x8B. At 25°C, typical readback is 512; resolution is ~0.5°C/LSB. Calibration is factory-trimmed and does not require user compensation - specified in ADC Electrical Characteristics (page 8).
Is the MPM54313GBJ-0000-T RoHS and REACH compliant?
Yes - all MPS parts, including MPM54313GBJ-0000-T, are lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as stated in the Applications section (page 2) and Quality Assurance documentation on monolithicpower.com.
What is the minimum required input capacitance for stable operation?
The typical application circuit specifies 22µF × 6 ceramic capacitors (132µF total) on VIN. Minimum effective capacitance must maintain <100mV input ripple at full load; 100µF low-ESR X7R/X5R ceramics placed close to VIN/GND pins meet this requirement across 4–16V input range - validated in Efficiency vs. Load Current curves (pages 10–12).
