Product details
Overview
LM3410YQMF/NOPB from Texas Instruments is a 525-kHz constant-current boost/SEPIC LED driver IC with internal 170-mΩ NMOS switch, 190-mV feedback reference, and PWM dimming capability. It operates from 2.7 V to 5.5 V input, delivers up to 24 V output, and regulates LED current via external sense resistor-used in automotive interior lighting, handheld device backlighting, and HB-LED flash circuits.
For engineers reviewing the LM3410YQMF/NOPB datasheet, LM3410YQMF/NOPB pinout, LM3410YQMF/NOPB application, or LM3410YQMF/NOPB equivalent, key selection criteria include switching frequency (525 kHz), thermal shutdown threshold (165°C), duty cycle range (2–95%), internal compensation, and AEC-Q100 Grade 1 qualification for –40°C to 125°C ambient operation.
Technical Context
The LM3410YQMF/NOPB implements current-mode PWM control with fixed 525-kHz oscillator, cycle-by-cycle current limiting (2.8-A typical peak), and internal soft-start. Its error amplifier compares FB voltage against 190-mV reference to adjust duty cycle, enabling precise constant-current regulation independent of LED forward voltage variation.
It supports both boost and SEPIC topologies using minimal external components: one inductor, one Schottky diode, two capacitors, and one feedback resistor. The DIM pin accepts 1 Hz–25 kHz PWM signals for brightness control, while shutdown mode draws only 80 nA quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching frequency | 525 kHz - enables use of sub-2.2-µH inductors and compact ceramic capacitors |
| Feedback reference voltage | 190 mV ±12 mV - sets LED current via RSET = 0.19 V / ILED, stable over temperature |
| Input voltage range | 2.7 V to 5.5 V - compatible with single-cell Li-ion, USB, and 3.3-V/5-V rails |
| Output voltage capability | Up to 24 V - supports strings of 6+ white LEDs or high-VF HB-LEDs |
| Internal switch RDS(on) | 170 mΩ (typ) - limits conduction loss at 2.8-A peak, enabling >88% efficiency |
| Thermal shutdown | 165°C activation - protects die during overload or poor PCB thermal design |
| Shutdown current | 80 nA - preserves battery life in portable devices during standby |
Pinout & Package
LM3410YQMF/NOPB is housed in a thermally enhanced 6-pin WSON package (3.0 mm × 3.0 mm, 0.75-mm height) with exposed thermal pad (DAP) connected to PGND/AGND. The DAP requires ≥4 vias to inner-layer ground plane for effective heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Switch node output | Drives inductor anode; swings from GND to VOUT + VF(D1); must be routed short and wide |
| 2 - GND | Signal ground | Reference for FB and DIM; connect bottom of RSET here; separate from PGND in layout |
| 3 - FB | Current-sense feedback input | Monitors voltage across RSET; regulates ILED = 0.19 V / RSET; high-impedance (≤1 µA bias) |
| 4 - DIM | PWM dimming/shutdown control | Logic-high (>1.8 V) enables operation; 0–100% PWM duty controls average ILED; sink/source ≤100 nA |
| 5 - VIN | Power input supply | Supplies gate drive and bias circuitry; requires local 2.2–22 µF MLCC with low ESL |
| DAP | Thermal & power ground | Die attach pad tied to PGND/AGND; mandatory for thermal performance and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (–40°C to 125°C) and ESD robustness (HBM ±2 kV, CDM ±1 kV) |
| Internal compensation | Eliminates need for external compensation network-reduces BOM count and layout sensitivity |
| Current-mode PWM control | Provides inherent cycle-by-cycle current limiting and fast transient response to LED load changes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar constant-current LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3410XQMF/NOPB | 1.6-MHz switching frequency; higher RDS(on) (190 mΩ typ); 88–92% max duty cycle | Better suited for ultra-compact layouts needing <1-µH inductors; less efficient at high ILED due to higher conduction loss | Select when board space is constrained and input voltage is stable; avoid if thermal margin is tight at >500 mA |
| TPS61061DRVR | 600-kHz fixed frequency; 1.2-A switch limit; no internal compensation; requires external RC network | Lower peak current rating limits use to ≤350 mA LED strings; lacks AEC-Q100 qualification | Choose for cost-sensitive non-automotive designs where 1.2-A peak suffices and layout can accommodate compensation components |
Compared with LM3410YQMF/NOPB, LM3410XQMF/NOPB trades thermal headroom for smaller magnetics, while TPS61061DRVR offers lower cost but requires more design effort and lacks automotive qualification-making LM3410YQMF/NOPB optimal for thermally demanding, safety-conscious, or space-constrained AEC-Q100 applications.

FAQ
What is the maximum LED string voltage supported by the LM3410YQMF/NOPB?
The LM3410YQMF/NOPB supports output voltages up to 24 V, enabling series strings of up to six standard white LEDs (VF ≈ 3.3 V each) or four high-VF HB-LEDs. This limit is defined by the absolute maximum SW pin voltage rating of 26.5 V and practical efficiency constraints above 24 V in boost configuration.
Does the LM3410YQMF/NOPB require external compensation components?
No, the LM3410YQMF/NOPB features fully internal compensation, eliminating the need for external RC networks. This simplifies design, reduces BOM count, and improves stability across input voltage, load, and temperature variations-confirmed in TI's SNVS541H datasheet Section 7.1 and Figure 10.
How does the DIM pin function on the LM3410YQMF/NOPB?
The DIM pin on the LM3410YQMF/NOPB serves dual functions: logic-level enable (high = active, low = shutdown) and analog PWM dimming input. Applying a 1 Hz–25 kHz PWM signal with 0–100% duty cycle directly controls average LED current, with optimal resolution achieved at 200 Hz–1 kHz per TI's application note SLVA422.
What thermal considerations apply to the LM3410YQMF/NOPB in the WSON package?
The LM3410YQMF/NOPB in 6-pin WSON (NGG) has RθJA = 55.3°C/W at 0 LFPM airflow. Effective thermal design requires soldering the exposed DAP to a minimum 100-mm² copper area with ≥4 thermal vias to an internal ground plane. Junction temperature must remain below 125°C continuous and 165°C peak to avoid thermal shutdown.
Is the LM3410YQMF/NOPB qualified for automotive applications?
Yes, the LM3410YQMF/NOPB is AEC-Q100 qualified as Grade 1 (–40°C to +125°C ambient), with HBM ESD rating ±2 kV and CDM rating ±1 kV. This qualification is explicitly stated in the "Features" section of the official SNVS541H datasheet and applies to the Q1 suffix variants-including LM3410YQMF/NOPB.
