Product details
Overview
MPQ3410DJ-AEC1-LF-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, synchronous rectified step-up DC/DC converter delivering up to 6V output from 1.8V–6V input, with 1.3A typical switch current limit, 550kHz fixed switching frequency, and internal soft-start. It integrates N- and P-channel MOSFETs, provides output-to-input disconnect in shutdown, and targets automotive infotainment power rails requiring high efficiency (>90%) and thermal robustness (–40°C to +125°C).
For engineers reviewing the MPQ3410DJ-AEC1-LF-Z datasheet, MPQ3410DJ-AEC1-LF-Z pinout, MPQ3410DJ-AEC1-LF-Z application, or MPQ3410DJ-AEC1-LF-Z equivalent, key selection criteria include its AEC-Q100 qualification, TSOT23-5 package footprint, feedback voltage of 1.19V ±0.05V, zero-current shutdown mode, and integrated synchronous rectification for minimal external component count in space-constrained automotive modules.
Technical Context
The MPQ3410DJ-AEC1-LF-Z employs a fixed-frequency (550kHz), current-mode control architecture with internal 1.2V reference and error amplifier. Its regulation loop compares FB voltage against this reference and modulates peak inductor current via PWM comparator and ramp generator.
It features dual-MOSFET integration: low-side N-channel switch (RONLS = 300mΩ) and high-side P-channel synchronous rectifier (RONHS = 530–700mΩ), enabling bidirectional isolation during shutdown and eliminating external diode losses. Thermal shutdown triggers at 160°C with 30°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | 2.5V to 6.0V - supports common automotive logic rails (3.3V, 5V) and sensor biasing without external LDO post-regulation. |
| Switching Frequency | 550kHz (±240kHz over temp) - enables compact 4.7µH inductors and <10µF ceramic output capacitors, reducing board area by >30% vs. 1MHz+ converters. |
| Feedback Voltage | 1.19V ±0.05V - sets precise output via resistive divider; tolerance directly defines output accuracy (e.g., ±4.2% for 5V output with 1% resistors). |
| Max Switch Current | 1.3A typical - limits peak inductor current to sustain ≥400mA continuous output at 5V from 2.5V input with >85% efficiency. |
| Shutdown Supply Current | 0.5µA max - ensures negligible battery drain in always-on automotive modules (e.g., telematics wake-on-LIN). |
| Operating Junction Temp | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and dashboard-mounted electronics. |
| Thermal Resistance θJA | 220°C/W - requires minimal copper pour (≥100mm²) on GND layer to maintain TJ <125°C at 300mA load in ambient 85°C. |
Pinout & Package
MPQ3410DJ-AEC1-LF-Z uses a 5-pin TSOT23-5 package (0.95mm pitch, 2.9mm × 1.6mm footprint) with exposed pad for thermal dissipation. Pin 1 is FB, pin 2 is GND, pin 3 is OUT, pin 4 is SW, and pin 5 is EN - all pins are surface-mount compatible with standard reflow profiles (MSL Level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Regulation Feedback Input | Connects to voltage divider midpoint; 50nA input bias enables high-impedance dividers (e.g., 100kΩ/220kΩ) minimizing quiescent current loss. |
| GND (Pin 2) | Power Ground Reference | Primary return path for switch current and error amplifier; must be tied to low-impedance ground plane adjacent to SW and OUT pins. |
| OUT (Pin 3) | Output Supply Rail | Provides regulated output voltage; connects to output capacitor and load; internal P-MOSFET source ties here for output disconnect. |
| SW (Pin 4) | Switching Node | Drain node of both internal MOSFETs; connects to inductor; requires short, low-inductance trace to minimize EMI and voltage overshoot. |
| EN (Pin 5) | Enable Control Input | Logic-level input (0.4V low / ≥1.05V high at VIN=1.8V); enables zero-current shutdown with 0.5µA supply current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Synchronous Rectification | Eliminates external Schottky diode in most 3.3V/5V applications, reducing BOM cost and improving efficiency by 5–8% at light loads. |
| Output-to-Input Disconnect | Physically isolates VOUT from VIN during shutdown via P-MOSFET body diode reversal, preventing backfeed into weak input sources (e.g., coin-cell backup). |
| Internal Soft-Start Timer | Gradually ramps error amplifier output to limit inrush current, enabling safe startup into 100µF output capacitance without input voltage sag. |
| AEC-Q100 Grade 1 Qualification | Validated for automotive operation from –40°C to +125°C junction temperature, including HTOL, TC, and ESD testing per AEC-Q100-002/-011. |
| Fixed 550kHz Switching | Enables predictable EMI filtering with single-stage LC filter; avoids AM band interference while maintaining small magnetics size. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610995RTER | Higher 1.5A switch current, 1.225V FB voltage, but no AEC-Q100 qualification; 1.2MHz switching increases EMI risk. | Targets industrial handhelds, not automotive; lacks thermal shutdown hysteresis and MSL1 packaging. | Select only for non-automotive designs needing higher peak current and faster transient response. |
| MAX17222ETA+ | Lower 0.5A switch current, 500kHz switching, AEC-Q100 Grade 2 (–40°C to +105°C), no output disconnect. | Suitable for cabin interior modules only; cannot support under-hood thermal stress or backfeed isolation. | Choose when cost sensitivity outweighs thermal margin and isolation requirements. |
Compared with TPS610995RTER and MAX17222ETA+, MPQ3410DJ-AEC1-LF-Z uniquely combines AEC-Q100 Grade 1, output disconnect, and 1.3A capability in TSOT23-5-enabling single-chip 5V generation for safety-critical automotive subsystems where reliability and physical isolation are mandatory.

FAQ
What is the minimum input voltage required for MPQ3410DJ-AEC1-LF-Z to start regulation?
The MPQ3410DJ-AEC1-LF-Z has a startup supply voltage (VST) of 1.4V minimum across –40°C to +125°C. At 25°C, it starts regulation at 1.5V, enabling operation from partially discharged Li-ion cells (e.g., 2.5V nominal down to 2.0V) in automotive backup systems.
Does MPQ3410DJ-AEC1-LF-Z require an external Schottky diode?
No external Schottky diode is required for outputs ≤4V. For 5V output applications, MPS recommends adding a 0.5A, 20V Schottky diode (e.g., RB520S-30) in parallel with the internal P-MOSFET to clamp SW node voltage and prevent breakdown during heavy load transients.
How does the output disconnect feature function during shutdown?
When EN is pulled low (<0.4V), both internal MOSFETs turn off. The P-MOSFET's body diode orientation blocks reverse current flow from OUT to SW, physically isolating the output rail from the input source and preventing backfeed into weak supplies like supercapacitors or backup batteries.
What is the recommended output capacitor value for stable 5V operation?
MPS specifies a minimum 4.7µF ceramic capacitor for 5V output, with 10µF recommended for improved transient response. X5R/X7R dielectrics with 10V rating are preferred; placement must be within 2mm of OUT and GND pins to minimize loop inductance.
Can MPQ3410DJ-AEC1-LF-Z operate with input voltage above 6V?
No. Absolute maximum VIN is +6.5V on all pins, and recommended operating VIN is limited to 1.8V–6.0V. Exceeding 6.0V risks permanent damage to the internal N-MOSFET gate oxide and violates AEC-Q100 stress test margins.
Is the FB pin internally compensated?
Yes. The MPQ3410DJ-AEC1-LF-Z includes internal compensation circuitry, eliminating the need for external Type-II or Type-III compensation networks. This reduces design complexity and PCB area while ensuring stable loop response across temperature and load conditions.
What is the thermal shutdown hysteresis value?
Thermal shutdown activates at 160°C junction temperature and releases at 130°C (30°C hysteresis), preventing rapid cycling during thermal overload events. This behavior is guaranteed by design and verified per AEC-Q100-004.
