Product details
Overview
MP2167AGQE-Z from Monolithic Power Systems is a 2.7V–6V input, 6A synchronous buck converter with configurable switching frequency (300kHz–2.2MHz), integrated 35mΩ/25mΩ MOSFETs, and selectable AAM/FCCM operation modes. It delivers 0.606V minimum output voltage with internal compensation and operates across –40°C to +125°C for portable instruments and battery-powered systems.
For engineers reviewing the MP2167AGQE-Z datasheet, MP2167AGQE-Z pinout, MP2167AGQE-Z application, or MP2167AGQE-Z equivalent, key selection criteria include light-load efficiency mode control (AAM vs FCCM), wettable-flank QFN-14 package compatibility, 42μA quiescent current, valley-current OCP protection, and SYNC clock interoperability up to 2.2MHz.
Technical Context
The MP2167AGQE-Z employs peak-current-mode control with internal compensation, enabling fast transient response and cycle-by-cycle current limiting without external loop components. Its dual-mode operation-AAM for high light-load efficiency 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 35mΩ high-side and 25mΩ low-side MOSFET, supports external synchronization via FREQ/SYNC pin (0.3–2.2MHz), and provides power-good indication with ±5% hysteresis on rising/falling thresholds relative to VFB. Thermal shutdown activates at 170°C with 25°C hysteresis and automatic recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 6V - supports single-cell Li-ion, USB PD, and industrial 3.3V/5V rails without pre-regulation. |
| Continuous Output Current | 6A - enables compact point-of-load conversion for FPGA cores, SoC I/O, or multi-rail PMIC subsystems. |
| Configurable Switching Frequency | 300kHz to 2.2MHz - allows trade-off between inductor size (high-f) and efficiency (low-f), adjustable via resistor or external SYNC clock. |
| Feedback Reference Voltage | 0.606V ±10mV - sets precise low-VOUT regulation (e.g., 1.0V, 1.2V, 1.8V) using standard resistor dividers. |
| Quiescent Current (AAM) | 42μA - minimizes standby power loss in always-on battery applications like wearables or IoT sensors. |
| Protection Features | Valley-current OCP, SCP, VIN UVLO (2.5V rise/2.15V fall), VOUT OVP (115% of VFB), thermal shutdown (170°C) - ensures robust fault handling without external circuitry. |
| Package | QFN-14 (3mm × 3mm, wettable flank) - supports automated optical inspection (AOI) and improves solder joint reliability in high-volume SMT assembly. |
Pinout & Package
MP2167AGQE-Z is housed in a thermally enhanced, wettable-flank QFN-14 (3mm × 3mm) package with exposed thermal pad (PGND-connected). The package supports reflow-compatible soldering and facilitates efficient heat dissipation in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 IN | Power input supply | Connects to 2.7–6V source; requires local 10μF ceramic decoupling capacitor placed adjacent to pins to suppress switching noise. |
| 3, 4 PGND | Power ground return | Low-impedance path for high di/dt currents; must be tied directly to large copper pour under IC and connected to input/output capacitor negatives. |
| 5 FREQ/SYNC | Frequency configuration & sync input | Resistor-to-GND sets fSW (300kHz–2.2MHz); accepts external clock up to 2.2MHz for system-level timing alignment. |
| 6 AGND | Analog reference ground | Separate ground for FB, SS, EN, MODE; must be star-connected to PGND at single point to avoid noise coupling into feedback path. |
| 7 FB | Output voltage feedback node | Connects to resistor divider tap; monitors VOUT for regulation and triggers PG and UVLO functions based on deviation from 0.606V reference. |
| 8 SS | Soft-start timing control | Capacitor-to-GND sets ramp time; floating enables internal 1ms soft-start to limit inrush current during power-up. |
| 9, 10 SW | Switch node | Drives external inductor; connects internally to HS/LS MOSFETs; requires short, low-inductance trace to minimize ringing and EMI. |
| 11 PG | Power-good open-drain indicator | Pulls high (to VIN) when VFB is within ±15% of 0.606V; used for sequencing or host MCU enable signaling. |
| 12 SYNCO | Synchronization output | 180° phase-shifted clock output for cascading multiple MP2167A devices to reduce input ripple and improve thermal distribution. |
| 13 MODE | Light-load operation mode select | Logic-low (≤0.4V) enables AAM for high efficiency at <100mA loads; logic-high (≥1.2V) forces FCCM for constant-frequency, low-noise operation. |
| 14 EN | Enable control input | Active-high (≥1.2V) enables converter; floating or grounded disables device with <1μA shutdown current. |
Key Features

| Integrated 35mΩ HS / 25mΩ LS MOSFETs | Eliminates need for external Schottky diode or discrete switches, reducing BOM count and board area while maintaining >90% efficiency at 3A load. |
| Selectably configurable AAM or FCCM mode | Enables dynamic optimization: AAM extends battery runtime in idle states; FCCM ensures predictable EMI profile and minimal output ripple in active processing. |
| Internal compensation network | Removes requirement for external Type-II/III compensation components, simplifying design validation and reducing layout sensitivity to parasitic effects. |
| 42μA quiescent current in AAM mode | Supports ultra-low-power sleep states in portable medical devices or sensor nodes where microamp-level leakage dictates system battery life. |
| Valley-current over-current protection | Detects current collapse at LS-FET turn-off to prevent runaway during short-circuit events, offering faster fault response than peak-only detection schemes. |
| Wettable flank QFN-14 package | Enables reliable automated optical inspection (AOI) of solder fillets on all 14 perimeter leads, improving manufacturing yield and field-reliability assurance. |

FAQ
What is the minimum output voltage supported by MP2167AGQE-Z?
The MP2167AGQE-Z supports a regulated output voltage as low as 0.606V, set by its internal reference voltage (VFB = 0.606V ±10mV). This enables direct generation of common low-voltage rails such as 0.8V, 0.9V, 1.0V, 1.2V, and 1.8V using standard resistor dividers without external amplification.
How does the MODE pin affect efficiency and output ripple?
When MODE is pulled low (<0.4V), the device enters Advanced Asynchronous Modulation (AAM) mode, skipping pulses under light load to reduce switching losses-yielding 42μA IQ and peak efficiency >92% at 10mA. When MODE is pulled high (>1.2V), it forces Forced Continuous Conduction Mode (FCCM), delivering fixed-frequency operation with lower output voltage ripple (<15mVpp) and predictable EMI behavior.
Can MP2167AGQE-Z synchronize to an external clock, and what is the valid frequency range?
Yes-the FREQ/SYNC pin accepts external clock signals from 0.3MHz to 2.2MHz. The device locks to the external clock edge and outputs a 180° phase-shifted signal on SYNCO, enabling interleaved operation with other MP2167A units or compatible converters to reduce input ripple and thermal hotspots.
What thermal protection mechanisms are implemented?
The MP2167AGQE-Z includes thermal shutdown that activates at 170°C junction temperature, with 25°C hysteresis for automatic recovery once temperature falls below 145°C. This protection is independent of load current and operates even during startup or fault conditions, preventing permanent silicon damage under sustained overload or poor heatsinking.
Is the QFN-14 package lead-free and RoHS-compliant?
Yes-MP2167AGQE-Z uses a lead-free, halogen-free, RoHS-compliant wettable-flank QFN-14 package. MPS confirms full compliance with EU RoHS Directive 2011/65/EU and provides material declarations and green status documentation on its official website under Quality Assurance resources.
Does MP2167AGQE-Z require external compensation components?
No-it features fully internal compensation, eliminating the need for external Type-II or Type-III compensation networks. This reduces component count, simplifies layout, and improves immunity to PCB parasitics-enabling robust performance across varying output capacitor ESR and load conditions without tuning.
What is the purpose of the PG (Power Good) signal, and how is it configured?
The PG pin is an open-drain output that pulls high to VIN when FB voltage is within ±15% of 0.606V, indicating stable regulation. It has built-in hysteresis (±5% of VFB) and 40–180μs delay on rising/falling edges. No pull-up is required-internal 1MΩ resistor connects PG to VIN-making it ready for direct connection to MCU reset or enable inputs.
