Product details
Overview
MPQ3413GJ-5-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified synchronous step-up DC/DC converter delivering a fixed 5V output at up to 0.3A average load, operating from 2.8V–4V input with 2.2MHz switching, 52μA quiescent current, and true output disconnect via integrated P-channel MOSFET. It targets automotive secondary regulation and single-cell Li-ion backup power rails.
For engineers reviewing the MPQ3413GJ-5-AEC1-Z datasheet, MPQ3413GJ-5-AEC1-Z pinout, MPQ3413GJ-5-AEC1-Z application, or MPQ3413GJ-5-AEC1-Z equivalent, key selection criteria include its AEC-Q100 qualification, <1μA shutdown current, internal soft start and compensation, 85% peak efficiency, and TSOT23-8 footprint compatibility with space-constrained automotive modules.
Technical Context
The MPQ3413GJ-5-AEC1-Z implements fixed-frequency (2.2MHz), current-mode PWM control with internal slope compensation and a 0.6V reference for feedback regulation. Its dual-MOSFET architecture integrates an N-channel high-side switch (70mΩ RDS(ON)) and P-channel synchronous rectifier (80mΩ RDS(ON)) enabling true output disconnect and inrush limiting during linear-charge startup.
It supports two operational modes: advanced asynchronous modulation (AAM) for light-load efficiency via frequency stretching, and forced continuous conduction mode (FCCM) for consistent 2.2MHz operation across full load range. Protection includes over-voltage (6V threshold), short-circuit recovery, and thermal shutdown (155°C trip, 130°C hysteresis).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 5V ±2.5% over -40°C to +125°C; enables direct USB-5V rail generation without external feedback resistors. |
| Input voltage range | 2.8V to 4V; supports single-cell Li-ion (2.8V cutoff) and automotive 3.3V auxiliary rails. |
| Switching frequency | 2.2MHz ±14%; allows use of sub-1μH inductors (e.g., 0.68μH) and compact ceramic capacitors (≥22μF COUT). |
| Quiescent current | 52μA at VIN=3.3V, no load; ensures minimal battery drain in always-on automotive subsystems. |
| Shutdown current | <1μA; achieved by complete P-channel MOSFET disconnect, enabling full output discharge and zero reverse leakage. |
| Peak efficiency | 85% at 0.3A, VIN=3.3V; enabled by synchronous rectification and low RDS(ON) MOSFETs eliminating Schottky diode loss. |
| Protection features | OVP (6V), SCP (auto-recovery), OTP (155°C/130°C hysteresis); provides autonomous fault handling without external circuitry. |
Pinout & Package
MPQ3413GJ-5-AEC1-Z is housed in a thermally enhanced TSOT23-8 package (2.9mm × 1.6mm × 0.85mm), optimized for automotive PCB layouts with exposed PGND pad for thermal dissipation and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Power input supply | Bias source during startup; must be locally bypassed; supplies internal circuits until VOUT exceeds VIN. |
| 2 OUT | Regulated output node | Drain of internal P-channel SR; sensing point for regulation; fully disconnected from IN in shutdown. |
| 3 SW | Switch node | Connection between internal N-channel and P-channel MOSFETs; requires short/wide PCB trace to minimize EMI and voltage spikes. |
| 4 PGND | Power ground | High-current return path for inductor and MOSFETs; tied to exposed thermal pad for heat dissipation. |
| 5 FTY | Factory test | No connection required in application; float or tie to GND per layout guidelines. |
| 6 AGND | Analog ground | Reference for error amplifier and feedback; must be separated from PGND and connected at single point near IC. |
| 7 MODE | Operating mode select | Logic-high enables AAM (light-load efficiency); logic-low forces FCCM (constant fSW); do not toggle during operation. |
| 8 EN | Enable control | Pull ≥1.2V to enable; ≤0.4V to enter shutdown with full output disconnect and <1μA IQ. |
Key Features
| Feature | Design Value |
|---|---|
| True output disconnect | Integrated P-channel MOSFET eliminates body diode conduction, enabling full VOUT discharge and zero reverse current in shutdown. |
| Internal soft start & compensation | Monolithic RC-based SS ramp and type-II compensation reduce external components to only inductor, CIN, and COUT. |
| Inrush current limiting | Linear-charge phase limits startup current to 0.3A (VOUT=0V) and 0.8A (VOUT=3.3V), protecting weak input sources. |
| AEC-Q100 Grade 1 qualification | Rated for -40°C to +125°C junction temperature with validated reliability testing per automotive stress standards. |
| Thermal protection with hysteresis | Shuts down at 155°C and resumes at 130°C, preventing thermal runaway while avoiding oscillation near trip point. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610995RTER | Fixed 5V output, 1.2MHz fSW, 300nA shutdown current, but lacks AEC-Q100 qualification and true output disconnect. | Suitable for industrial or consumer portable devices; not certified for automotive underhood or cabin environments. | Select when ultra-low shutdown current is critical and automotive qualification is unnecessary. |
| MAX17222ATA+T | 5V output, 2.5MHz fSW, 300nA IQ, AEC-Q100 Grade 2 (–40°C to +105°C), no integrated output disconnect MOSFET. | Valid for dashboard or center-stack applications with lower ambient temp requirement; requires external diode for disconnect. | Choose when higher ambient temperature margin is acceptable and external component count is not constrained. |

FAQ
What is the minimum input voltage required for MPQ3413GJ-5-AEC1-Z to start up and regulate 5V?
The MPQ3413GJ-5-AEC1-Z starts up from as low as 2.8V input, using linear-charge mode to pre-charge the output before entering boost switching. Below 2.8V, UVLO (1.65V threshold) disables operation to prevent unstable regulation.
Does MPQ3413GJ-5-AEC1-Z require external compensation components?
No. The MPQ3413GJ-5-AEC1-Z features fully internal compensation, eliminating the need for external RC networks. This simplifies design and improves stability across temperature and load variations without tuning.
How does the MODE pin affect efficiency and EMI performance?
When MODE is high, the device enters AAM mode, reducing switching frequency under light loads to cut switching losses and improve efficiency-but may increase low-frequency EMI. When MODE is low (FCCM), 2.2MHz operation ensures consistent EMI spectrum for easier filtering.
Can MPQ3413GJ-5-AEC1-Z drive a 500mA load continuously?
No. The MPQ3413GJ-5-AEC1-Z is rated for 0.3A average output current. While peak switch current reaches 3.6A, sustained >0.3A loads exceed thermal limits in TSOT23-8 and violate datasheet specifications-use larger packages or parallel solutions for higher current.
Is an external Schottky diode required for output protection?
No. Adding an external Schottky diode defeats the true output disconnect feature and risks reverse current flow. The integrated P-channel MOSFET provides both rectification and isolation-external diodes must be omitted per datasheet layout guidance.
What PCB layout practices are critical for achieving 85% efficiency?
Place COUT (22μF) and CIN (10μF) as close as possible to OUT/PGND and IN/SW respectively; use wide, short traces for SW and PGND; separate AGND from PGND and tie at one point near the IC; and maximize copper area under the exposed thermal pad.
Does MPQ3413GJ-5-AEC1-Z support adjustable output voltage?
No. MPQ3413GJ-5-AEC1-Z has a factory-trimmed fixed 5V output. For adjustable outputs, consider the MPQ3423 variant (0.6V reference, external resistor divider), which shares the same package and AEC-Q100 qualification.
