Product details
Overview
MPQ3410DJ-LF-Z from Monolithic Power Systems is a synchronous rectified step-up DC-DC converter with AEC-Q100 Grade 1 qualification, fixed 550kHz switching frequency, 1.3A typical switch current limit, and output-to-input disconnect in shutdown mode. It operates from 1.8V–6V input to deliver regulated 2.5V–6V output, targeting power rail generation in space-constrained automotive and industrial portable electronics.
For engineers reviewing the MPQ3410DJ-LF-Z datasheet, MPQ3410DJ-LF-Z pinout, MPQ3410DJ-LF-Z application, or MPQ3410DJ-LF-Z equivalent, key selection criteria include its integrated N/P-channel MOSFETs, internal soft-start and compensation, thermal shutdown at 160°C, and TSOT23-5 package compatibility with high-density PCB layouts.
Technical Context
The MPQ3410DJ-LF-Z implements a current-mode control architecture with a 1.2V internal reference and error amplifier, enabling stable regulation under dynamic load transients. Its PWM comparator compares sensed inductor current against the error voltage to determine switch timing, while the 550kHz oscillator sets fixed-frequency operation independent of load or line variation.
Shutdown mode disables both internal switches and isolates OUT from SW via the P-channel MOSFET's body diode reverse blocking, achieving true output disconnect. The EN pin supports logic-level control with VIN-dependent high-threshold (1.05V min at VIN=1.8V) and internal 1MΩ pull-down for reliable low-power state entry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8V to 6V - Supports single-cell Li-ion, NiMH, and wide-range battery inputs without external LDO pre-regulation. |
| Output Voltage Range | 2.5V to 6V - Programmable via external resistor divider; enables 3.3V, 5V, or custom rails for sensors, displays, and RF modules. |
| Switching Frequency | 550kHz (typ) - Enables compact 4.7µH inductors and ceramic capacitors, reducing solution footprint vs. lower-frequency boosters. |
| Peak Switch Current Limit | 1.3A (typ) - Sets maximum inductor energy transfer; defines usable output power ceiling at given VIN/VOUT ratio and efficiency. |
| Feedback Reference Voltage | 1.19V (typ) - High-accuracy internal reference enables ±1.5% output regulation over temperature and line/load conditions. |
| Thermal Shutdown Threshold | 160°C - Protects die during sustained overload or poor PCB thermal design; 30°C hysteresis prevents oscillation near trip point. |
| Shutdown Quiescent Current | 0.5μA (max) - Minimizes battery drain in standby; critical for always-on automotive subsystems and IoT edge nodes. |
Pinout & Package
MPQ3410DJ-LF-Z is housed in a 5-pin TSOT23-5 package (0.95mm pitch, 2.9mm × 1.6mm footprint), optimized for thermal performance and automated assembly. The thin profile (0.85mm max height) supports ultra-low-profile applications including wearables and slim automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback Input | High-impedance node sensing divided output voltage; connects to resistive divider to set VOUT; sensitive to noise-requires local decoupling and short trace routing. |
| 2 GND | Power Ground | Primary return path for switch current and IC bias; must be tied to low-impedance ground plane adjacent to SW and OUT pins to minimize EMI and voltage bounce. |
| 3 OUT | Output Supply Rail | Connects to output capacitor and load; carries full output current; internal P-MOSFET source ties here-enables output disconnect when disabled. |
| 4 SW | Switch Node | Drain connection of internal N-MOSFET and P-MOSFET; high dv/dt node requiring minimized loop area with inductor and input capacitor to reduce radiated emissions. |
| 5 EN | Enable Control | Logic-compatible input (0.4V low threshold); internal 1MΩ pull-down ensures default-off state; VIN-dependent high threshold avoids false turn-on during brown-out. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Rectification | Integrated P-channel MOSFET replaces external Schottky diode-reduces conduction loss by >30%, enabling >90% peak efficiency at mid-load. |
| Output Disconnect | True isolation between OUT and SW in shutdown-prevents backfeed into input source and enables clean power sequencing in multi-rail systems. |
| Internal Soft-Start | Programmed ramp on error amplifier output limits inrush current during startup-eliminates need for external soft-start capacitor or current-limiting resistor. |
| Fixed-Frequency Current-Mode Control | 550kHz clock + peak-current sensing delivers fast transient response (<10µs recovery) and inherent cycle-by-cycle current limiting for robust short-circuit protection. |
| AEC-Q100 Grade 1 Qualification | Validated for -40°C to +125°C operation with extended reliability testing-meets automotive infotainment, ADAS sensor, and body electronics requirements. |

FAQ
What is the minimum input voltage required for MPQ3410DJ-LF-Z to start regulation?
The MPQ3410DJ-LF-Z requires a minimum startup supply voltage of 1.4V (over temperature) to initiate regulation. At room temperature, startup occurs at 1.5V, and the device enters normal operation once the output crosses 1.6V. Below this threshold, the controller remains inactive even if EN is high.
Does MPQ3410DJ-LF-Z require an external Schottky diode?
An external Schottky diode is required only for output voltages ≥4V to clamp the SW node voltage and prevent overstress of the internal P-MOSFET. For 3.3V outputs, the internal synchronous rectifier suffices; for 5V designs, a 0.5A/20V Schottky (e.g., RB520S-30) is recommended per the datasheet Figure 3.
How does the EN pin behave with varying input voltage?
The EN pin's high-threshold voltage increases with VIN: 1.05V min at VIN=1.8V, 1.65V at VIN=3.3V, and 2.15V at VIN=5V. This adaptive threshold prevents false turn-on during input brown-out while ensuring reliable enablement across the full 1.8–6V input range.
Can MPQ3410DJ-LF-Z operate in discontinuous conduction mode (DCM)?
Yes-the MPQ3410DJ-LF-Z automatically transitions into DCM at light loads. Its current-mode architecture maintains stability in both CCM and DCM, and the feed-forward capacitor (up to 220pF across R1) improves ripple and transient response specifically in DCM operation.
What is the thermal resistance (θJA) of the TSOT23-5 package?
The junction-to-ambient thermal resistance (θJA) for MPQ3410DJ-LF-Z in TSOT23-5 is 220°C/W, measured on a standard 4-layer JEDEC JESD51-7 test board. With a maximum junction temperature of 125°C and ambient of 25°C, the maximum continuous power dissipation is 0.45W before thermal shutdown activates.
Is the feedback reference voltage trimmed during production?
Yes-the 1.19V feedback reference voltage is factory-trimmed to ±1% tolerance at 25°C and maintains ±1.5% over the full -40°C to +125°C operating range. This trimming ensures accurate output voltage setting without requiring post-assembly calibration.
What layout practices are critical for stable MPQ3410DJ-LF-Z operation?
Place input capacitor (≥4.7µF ceramic) within 2mm of VIN and GND pins; route SW and OUT traces wide and short; tie FB divider ground directly to GND pin-not system ground; use solid ground plane under IC; avoid routing noisy signals near FB or EN pins.
