Product details
Overview
MPQ2167AGQE-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade-1 qualified, frequency-configurable (300kHz–2.2MHz) synchronous buck converter delivering up to 6A continuous output current from a 2.7V–6.0V input, with 0.606V minimum output voltage and integrated 35mΩ/25mΩ MOSFETs. It supports selectable advanced asynchronous mode (AAM) or forced continuous conduction mode (FCCM), features internal compensation, and targets automotive infotainment, clusters, and telematics power rails.
For engineers reviewing the MPQ2167AGQE-AEC1-P datasheet, MPQ2167AGQE-AEC1-P pinout, MPQ2167AGQE-AEC1-P application, or MPQ2167AGQE-AEC1-P equivalent, key selection considerations include its wettable-flank QFN-14 package, valley-current-based OCP with 7A limit, 42μA quiescent current in AAM, PG indicator with ±5% hysteresis, and SYNC capability up to 2.2MHz for multi-rail timing coordination.
Technical Context
The MPQ2167AGQE-AEC1-P employs peak-current-mode control with internal slope compensation and a dedicated valley-current detection circuit for cycle-by-cycle over-current protection. Its dual-mode operation-AAM for ultra-low IQ at light load and FCCM for fixed-frequency low-ripple regulation-is selected via the MODE pin's logic level (≤0.4V for AAM, ≥1.2V for FCCM).
It integrates a high-precision 0.606V reference (±1.7% over –40°C to +125°C), uses FB as the sole feedback node for regulation, UVLO, and PG monitoring, and provides 180° phase-shifted SYNCO output for synchronized multi-phase designs. The FREQ/SYNC pin accepts either a resistor for frequency setting or an external clock signal up to 2.2MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6.0V - supports direct connection to automotive 3.3V/5V rails and battery-backed systems without pre-regulation. |
| Output Current | 6A continuous - enables single-chip supply for SoC cores, DSPs, or FPGA I/O banks in automotive ECUs. |
| Switching Frequency | 300kHz to 2.2MHz - configurable via external resistor or external SYNC clock; allows optimization of size (high-f) vs. efficiency (low-f). |
| Quiescent Current | 42μA in AAM - minimizes standby power loss in always-on automotive modules such as telematics wake-up circuits. |
| Feedback Reference | 0.606V ±1.7% - enables precise low-VOUT regulation (e.g., 1.0V, 1.2V, 1.8V) with standard resistor dividers and tight load regulation. |
| OCP Threshold | 7A valley-current limit - prevents MOSFET thermal runaway during short-circuit events while maintaining robust transient response. |
| Thermal Shutdown | 170°C with 25°C hysteresis - ensures reliable auto-recovery under sustained overload or poor PCB thermal design. |
Pinout & Package
MPQ2167AGQE-AEC1-P is housed in a wettable-flank QFN-14 (3mm × 3mm) package, optimized for automated optical inspection (AOI) and high-reliability automotive solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 IN | Power input | Primary VIN connection; requires local 10μF ceramic decoupling directly at pins to suppress switching noise. |
| 3, 4 PGND | Power ground return | Low-impedance path for high di/dt switch currents; must connect to large copper pour shared with input/output capacitors. |
| 5 FREQ/SYNC | Frequency configuration & synchronization | Resistor-to-GND sets fSW; external clock input synchronizes multiple converters to eliminate beat frequencies. |
| 6 AGND | Analog reference ground | Isolated ground for error amplifier, reference, and soft-start circuitry; must be star-connected to PGND at single point. |
| 7 FB | Feedback sensing node | Connects to resistor divider output; monitors VOUT for regulation, PG assertion, and UVLO detection. |
| 8 SS | Soft-start timing control | Capacitor-to-GND sets ramp time; floating enables internal 1ms default-prevents inrush into downstream capacitance. |
| 9, 10 SW | Switch node | Drives external inductor; carries full switching current; requires tight layout to minimize EMI and voltage spikes. |
| 11 PG | Power-good open-drain output | Pulled high to VIN when VFB is within ±15% of 0.606V; used for sequencing or system reset assertion. |
| 12 SYNCO | Synchronization output | 180° out-of-phase clock signal for cascading or interleaving with other MPQ2167A devices. |
| 13 MODE | Light-load operation mode select | Logic-low = AAM (variable frequency); logic-high = FCCM (fixed frequency); floating not allowed. |
| 14 EN | Enable control input | Active-high enable with 1.2V threshold; internal 1MΩ pulldown allows simple pull-up or microcontroller GPIO drive. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | 35mΩ high-side + 25mΩ low-side MOSFETs - eliminates external Schottky diode and reduces BOM count and board area. |
| Internal Compensation | Single-type-II compensation network embedded - removes need for external compensation components and simplifies loop tuning. |
| Auto-Recovery Thermal Protection | 170°C trip with 25°C hysteresis - restores operation after cooling, avoiding system latch-up during transient overloads. |
| Valley-Current OCP | Detects current at MOSFET turn-off edge - avoids false triggering during high dV/dt transients and improves fault accuracy. |
| Wettable Flank Package | QFN-14 with solderable side walls - enables AOI-compatible reflow and meets IPC-A-610 Class 3 requirements for automotive production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ2169GQ-AEC1-Z | Same architecture but rated for 4A output; smaller 3mm×2mm QFN-10 package; lacks SYNCO pin. | Lower current capacity limits use in high-performance SoC rails; no synchronization support restricts multi-rail noise management. | Select only for space-constrained, ≤4A automotive modules where rail coordination is unnecessary. |
| TPS546B24RVFT | 6A, 1.5V–16V input; PMBus interface; external compensation; larger 4mm×4mm QFN-24 package. | Supports digital telemetry and dynamic margining but requires additional communication lines and layout area. | Choose when telemetry, remote configuration, or higher VIN range (>6V) is required-adds complexity and cost. |
Compared with MPQ2167AGQE-AEC1-P, MPQ2169GQ-AEC1-Z trades current capability and synchronization for footprint reduction, while TPS546B24RVFT adds digital control at the expense of analog simplicity, board area, and component count.

FAQ
What is the maximum allowable input voltage for MPQ2167AGQE-AEC1-P?
The absolute maximum VIN rating is +6.5V, but the recommended operating range is 2.7V to 6.0V. Operation above 6.0V risks exceeding internal MOSFET breakdown limits and invalidates AEC-Q100 qualification conditions. Transient spikes beyond 6.5V-even sub-10ns-may cause permanent damage per Absolute Maximum Ratings table.
How does the MODE pin affect light-load efficiency?
When MODE is pulled low (<0.4V), the device enters Advanced Asynchronous Mode (AAM), reducing switching frequency proportionally to load to minimize gate and switching losses-achieving 42μA IQ. When pulled high (>1.2V), Forced Continuous Conduction Mode (FCCM) maintains fixed frequency and lower output ripple, at the cost of higher light-load IQ.
Can MPQ2167AGQE-AEC1-P operate with 100% duty cycle?
Yes-the device supports 100% duty cycle operation, enabling dropout regulation when VIN approaches VOUT. This is critical for automotive cold-crank scenarios where input may dip to 2.7V while maintaining 3.3V or 2.5V outputs without interruption.
What is the purpose of the SYNCO pin?
SYNCO outputs a 180° phase-shifted clock signal synchronized to the internal oscillator or external SYNC input. It enables interleaved operation with a second MPQ2167A to halve input/output ripple current and reduce EMI without external timing controllers.
Is external compensation required for stability?
No-MPQ2167AGQE-AEC1-P uses internal Type-II compensation, eliminating external RC networks. Stability is guaranteed across all valid output capacitor ESR ranges and inductor values specified in the datasheet, provided layout follows MPS reference design guidelines.
How is over-voltage protection (OVP) implemented?
OVP triggers when FB voltage exceeds 115% of the 0.606V reference (≈0.697V), causing immediate shutdown and auto-recovery after thermal cooldown. Unlike many competitors, this OVP is independent of the error amplifier and responds within 100ns to fast transients.
Does the PG pin require an external pull-up resistor?
No-PG is an open-drain output with an internal pull-up to VIN. It asserts high (within 300mV of VIN) when FB is within ±15% of 0.606V and pulls low during fault or startup. External pull-up is unnecessary and may interfere with timing.
