Product details
Overview
MPQ2286GLE-0000-AEC1-P from Monolithic Power Systems is a programmable, AEC-Q100 Grade 1 qualified synchronous buck regulator with integrated 6mΩ high-side and 4mΩ low-side MOSFETs, delivering up to 12A output current from a 2.7V–6V input. It features ZDP™ zero-delay PWM control, configurable 2–4MHz switching frequency, differential VOUT sensing, and digital I²C interface with OTP memory for automotive point-of-load applications including ADAS and SoC core rails.
For engineers reviewing the MPQ2286GLE-0000-AEC1-P datasheet, MPQ2286GLE-0000-AEC1-P pinout, MPQ2286GLE-0000-AEC1-P application, or MPQ2286GLE-0000-AEC1-P equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 1.0% output regulation accuracy, programmable slew rate (1.25–10 mV/µs), thermal warning/shutdown thresholds (125°C/155°C), and support for forced CCM via SYNCIN or digital command.
Technical Context
The MPQ2286 implements a fixed-frequency, zero-delay PWM (ZDP™) architecture with internal compensation and dual-mode operation-DCM at light load and FCCM under synchronization or digital enable. Its digital interface supports packet error checking (PEC), multi-page OTP configuration, and real-time fault reporting including OCP, SCP, OVP, and thermal events.
It integrates a 3.3V internal LDO (VDRV) with 100mA current limit, bootstrap circuitry with 2.5V UVLO, and synchronized spread-spectrum modulation (±7.5% frequency spread at 9kHz rate) to reduce EMI. The device uses differential remote sensing (VOUT+/VOUT−) and supports programmable power-good thresholds with deglitching (20µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
MPQ2286GLE-0000-AEC1-P is housed in a wettable-flank QFN-18 package (3mm × 4mm, 0.5mm pitch), optimized for automated optical inspection (AOI) and high-reliability automotive solder joint formation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SYNCIN) | External clock input | Synchronizes internal oscillator to external source; enables FCCM without digital command; pulled down internally if unused |
| 2 (VOUT−), 3 (VOUT+) | Differential output sense | Enables precise remote sensing across PCB trace resistance; rejects common-mode noise on feedback path |
| 4 (EN) | Enable control | Logic-level input (1.2V threshold); 200kΩ internal pull-down allows floating for default-enable operation |
| 5,12 (VIN) | Main power input | Supplies control logic, LDO, and power switches; dual pins reduce IR drop and improve thermal spreading |
| 6,11 (PGND) | Power ground return | Low-inductance return path for high di/dt switch node current; internally connected to minimize loop area |
| 7 (BST) | Bootstrap supply | Drives high-side gate; requires 0.22µF capacitor to SW for charge replenishment each cycle |
| 8,9 (SW) | Switch node | Connects to inductor; carries full AC current; layout critical for EMI and efficiency |
| 10 (VDRV) | LDO decoupling & supply | Internal 3.3V LDO output; requires 4.7µF capacitor to PGND and 2.2Ω series resistor from VCC |
| 13 (PG) | Power-good indicator | Open-drain output; asserts low when VOUT out-of-regulation or fault detected; configurable via register |
| 14 (VCC) | Analog/digital supply | Input to internal LDO; requires 2.2µF capacitor to AGND and 2.2Ω resistor to VDRV |
| 15 (AGND) | Analog reference ground | Separate from PGND to isolate sensitive feedback and ADC circuits from power-switch noise |
| 16 (SYNCOUT) | Sync clock output | 0° or 180° phase-aligned output for cascading multiple regulators; floatable if unused |
| 17 (SDA), 18 (SCL) | I²C data/clock | Open-drain ports requiring external pull-ups; SDA supports PEC; both tolerate 1.2V–3.6V logic levels |
Key Features
| Feature | Design Value |
|---|---|

| Programmable slew rate (1.25–10 mV/µs) | Prevents overshoot during startup/shutdown and enables controlled voltage ramping for DDR termination or FPGA configuration sequencing |
| Spread-spectrum modulation | Reduces peak EMI by ±7.5% frequency dither at 9kHz, easing compliance with CISPR 25 Class 5 automotive emissions limits |
| Multi-page OTP memory | Stores factory-configured settings (VOUT, fSW, protections) and user-defined parameters; eliminates need for external EEPROM or MCU-based initialization |
| AEC-Q100 Grade 1 qualification | Validated for operation from −40°C to +125°C ambient with full electrical characterization and reliability stress testing per automotive standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ2285GLE-0000-AEC1-P | 8A output rating, identical pinout and feature set except reduced current capability and no VDRV LDO | Suitable for lower-power ADAS sensors or infotainment peripherals where 12A headroom is unnecessary | Select when system load is ≤8A and cost optimization is prioritized over future scalability |
| TPS628641ARGRR | 12A, 2.7–6V input, but lacks differential sensing, OTP, and AEC-Q100 Grade 1 qualification (only Grade 2) | Applicable in non-safety-critical industrial or consumer-grade automotive accessories | Choose only for non-automotive or Grade 2-compliant designs; not suitable for ADAS or powertrain-adjacent use cases |
Compared with MPQ2286GLE-0000-AEC1-P, the MPQ2285 offers cost savings at 8A capacity but sacrifices VDRV and design flexibility, while the TPS628641 lacks automotive qualification and precision sensing-making the MPQ2286 the sole option meeting full AEC-Q100 Grade 1, differential sensing, and programmable power-good requirements.

FAQ
What is the purpose of the VDRV pin, and how must it be decoupled?
VDRV is the output of an internal 3.3V LDO supplying analog and digital circuitry. It requires a 4.7µF ceramic capacitor to PGND and a 2.2Ω resistor between VCC and VDRV to stabilize regulation and limit inrush current. Failure to properly decouple VDRV causes erratic digital interface behavior and unstable feedback loop operation.
How does the MPQ2286 achieve ±1% output voltage accuracy?
The ±1% accuracy is achieved through factory-trimmed internal reference, differential VOUT+/VOUT− sensing that rejects PCB IR drop, and closed-loop regulation using internal compensation. It applies only for VOUT ≥ 0.5V × VOUT_SCALE; lower outputs use mV-level tolerances (±5mV or ±10mV) based on scaling mode selection.
Can the MPQ2286 operate without the digital interface enabled?
Yes. The MPQ2286 operates autonomously using factory-programmed OTP settings for VOUT, fSW, and protections. SDA/SCL pins may be tied to GND if unused. All critical functions-including enable, power-good, and fault protection-remain fully operational without I²C communication.
What thermal protection mechanisms are implemented, and how do they differ?
The MPQ2286 features two independent thermal responses: thermal warning at 125–155°C (configurable) triggers a flag via digital interface or PG assertion, while thermal shutdown at 155–185°C disables switching and holds the device in hiccup mode until junction cools below hysteresis threshold (20°C).
Is the MPQ2286GLE-0000-AEC1-P pin-compatible with other MPQ228x variants?
Yes-MPQ2286, MPQ2285, and MPQ2284 share identical QFN-18 (3mm×4mm) pinout and footprint. However, current rating, OTP content, and certain register defaults differ; hardware replacement requires validation of thermal margin and firmware register mapping.
What is the minimum off-time specification, and why does it matter for high-frequency operation?
The minimum off-time is 80ns, enabling reliable operation at 4MHz switching frequency with typical 0.75V output. This parameter constrains the lowest achievable output voltage at high fSW-e.g., at 4MHz and 2.7V input, the theoretical minimum VOUT is ~0.21V, matching the device's 0.20625V lower limit.
Does the MPQ2286 support forced continuous conduction mode (FCCM) without external synchronization?
Yes. FCCM can be activated either by applying an external clock to SYNCIN or via the digital interface by writing to the MODE register. In FCCM, the regulator maintains constant switching frequency regardless of load, improving ripple and EMI predictability at light loads.
