Product details
Overview
MPQ2167AGQE-AEC1-Z 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 automotive infotainment power rails requiring high efficiency, compact size, and robust protection in -40°C to +125°C environments.
For engineers reviewing the MPQ2167AGQE-AEC1-Z datasheet, MPQ2167AGQE-AEC1-Z pinout, MPQ2167AGQE-AEC1-Z application, or MPQ2167AGQE-AEC1-Z equivalent, this device offers selectable AAM/FCCM operation, external SYNC capability up to 2.2MHz, 42μA quiescent current, cycle-by-cycle OCP with valley detection, and wettable flank QFN-14 packaging for automotive-grade solder joint inspection.
Technical Context
The MPQ2167AGQE-AEC1-Z employs peak-current-mode control with internal compensation, enabling fast transient response without external loop components. Its dual-mode operation-advanced asynchronous mode (AAM) below 0.4V on MODE pin and forced continuous conduction mode (FCCM) above 1.2V-directly governs light-load efficiency versus output ripple trade-offs.
Switching frequency is set via resistor on FREQ/SYNC pin (300kHz–2.2MHz range) or synchronized externally up to 2.2MHz; SYNCO provides 180° out-of-phase clock for multi-phase coordination. Protection architecture includes valley-current OCP, short-circuit recovery, 170°C thermal shutdown with 25°C hysteresis, and ±15% PG window referenced to 0.606V FB threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6.0V - Supports wide automotive battery transients including cold-crank (2.7V) and load-dump (6.0V) conditions. |
| Output Current | 6A continuous - Delivers full rated current at TJ ≤ 125°C with QFN-14 package and standard PCB layout. |
| Feedback Voltage | 0.606V ±10mV - Enables precise low-voltage regulation (e.g., 1.2V with 1:1 divider) with <±0.5% line/load regulation. |
| Quiescent Current | 42μA in AAM - Minimizes standby power loss in always-on automotive modules such as telematics wake-up circuits. |
| Switching Frequency | Configurable 300kHz–2.2MHz - Allows optimization of inductor size (e.g., 1μH at 2.1MHz) and EMI profile across applications. |
| Protection Features | OCP (valley detection), SCP, OVP (115% VFB), UVLO (2.5V rising), thermal shutdown (170°C) - Fully autonomous fault handling without host intervention. |
| Package | QFN-14 (3mm × 3mm) with wettable flanks - Enables automated optical inspection (AOI) of solder joints per automotive manufacturing requirements. |
Pinout & Package
MPQ2167AGQE-AEC1-Z is housed in a thermally enhanced, lead-free, wettable flank QFN-14 (3mm × 3mm) package with exposed thermal pad. Pin numbering follows top-view orientation; PGND and IN pins are paired for low-inductance input path routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 IN | Power input supply | Primary VIN connection; requires local 10μF ceramic decoupling placed adjacent to pins to suppress switching noise. |
| 3, 4 PGND | Power ground return | Low-impedance return path for high di/dt currents; must connect directly to large copper pour under IC and capacitor negatives. |
| 5 FREQ/SYNC | Frequency configuration & sync input | Resistor-to-GND sets fSW; external clock up to 2.2MHz overrides internal oscillator for synchronized multi-rail systems. |
| 6 AGND | Analog reference ground | Separate ground for feedback, error amp, and bias circuitry; must be star-connected to PGND at single point near FB pin. |
| 7 FB | Output voltage feedback node | Connects to resistor divider tap; monitors VOUT for regulation and enables PG, UVLO, and OVP functions. |
| 8 SS | Soft-start timing control | Capacitor-to-GND sets ramp time; floating enables internal 1ms default-prevents inrush current during power-up. |
| 9, 10 SW | Switch node | Drives external inductor; connects internally to HS/LS MOSFETs; requires tight layout to minimize ringing and EMI. |
| 11 PG | Power good open-drain indicator | Pulled high to VIN when VFB within ±15%; signals stable regulation to MCU or PMIC sequencer with 40–180μs delay. |
| 12 SYNCO | Synchronization output | 180° phase-shifted clock output for interleaving with companion converters-reduces input/output ripple. |
| 13 MODE | Light-load operation mode select | Logic-low → AAM (efficiency-optimized); logic-high → FCCM (fixed-frequency, low-ripple); must not float. |
| 14 EN | Enable control input | Active-high enable with 1.2V threshold; internal 1MΩ pulldown allows direct MCU GPIO control without external resistor. |
Key Features

| Robust Protection Suite | Valley-current OCP, auto-recovery thermal shutdown, and 115% VFB overvoltage limit - Prevents latch-up during overload, short-circuit, or thermal stress without external supervision. |
| Automotive-Ready Packaging | Wettable flank QFN-14 - Supports AOI-based solder joint inspection required for IATF 16949-compliant automotive production lines. |
| Internal Compensation | Single-pole, single-zero compensation network embedded - Removes need for external compensation components, reducing layout complexity and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6286418ARQYR | Lower IQ (12μA), fixed 2.2MHz, no AAM mode, smaller 1.5mm×2mm DSBGA package | Better suited for ultra-low-power always-on nodes but lacks valley-current OCP and automotive qualification | Choose for space-constrained consumer wearables; avoid for AEC-Q100 systems or where valley-current protection is required. |

FAQ
What is the maximum allowable input voltage for MPQ2167AGQE-AEC1-Z?
The absolute maximum input voltage is +6.5V, but the recommended operating range is 2.7V to 6.0V. Operation beyond 6.0V risks exceeding internal MOSFET breakdown limits and may trigger permanent damage even if within absolute max ratings. Automotive cold-crank (2.7V) and nominal battery (12V/48V-derived 5V rails) fall safely within spec.
How does the MODE pin affect efficiency and output ripple?
When MODE is pulled low (<0.4V), the device enters Advanced Asynchronous Mode (AAM), reducing switching frequency under light load to cut gate and switching losses-boosting efficiency but increasing output ripple. When MODE is pulled high (>1.2V), Forced Continuous Conduction Mode (FCCM) maintains fixed frequency, minimizing ripple at the cost of higher light-load quiescent loss.
Can MPQ2167AGQE-AEC1-Z synchronize to an external clock above 2.2MHz?
No-the SYNC input accepts external clocks only within 0.3MHz to 2.2MHz. Attempting synchronization outside this range causes unpredictable behavior, including skipped cycles or failure to lock. The internal oscillator's upper limit is also 2.2MHz, so no operational benefit exists beyond this frequency.
Is the PG signal compatible with 1.8V logic interfaces?
Yes-PG is an open-drain output with internal pull-up to VIN. When VIN = 5V, PG pulls up to ~4.5V; when VIN = 3.3V, it reaches ~2.8V. For 1.8V logic, add an external pull-down resistor (e.g., 10kΩ) and level-shifter or use a logic buffer with 3.3V-tolerant inputs to ensure clean recognition of the PG high state.
Does the device require external compensation components?
No-MPQ2167AGQE-AEC1-Z features fully internal compensation with a single-pole, single-zero network optimized for stability with standard 1μH–4.7μH inductors and 22μF–47μF output capacitors. Adding external compensation will destabilize the loop and is neither recommended nor supported.
What thermal derating applies at 125°C ambient?
At TA = 125°C, the maximum continuous output current drops to approximately 3.2A due to junction temperature limits (TJ ≤ 150°C) and θJA = 60°C/W. Derating curves in the datasheet show linear reduction from 6A at 25°C ambient; PCB copper area and airflow significantly impact actual performance.
How is short-circuit protection implemented and recovered?
SCP triggers when valley current exceeds 7A for >100μs, forcing immediate shutdown. Recovery is automatic after thermal cooldown and removal of fault-no external reset needed. PG goes low during SCP and returns high only after VFB re-stabilizes within ±15%, ensuring safe re-engagement.
