Product details
Overview
LM3410XMYE/NOPB from Texas Instruments is a 1.6-MHz constant-current boost/SEPIC LED driver IC with internal NMOS switch (170 mΩ), 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 high-brightness LED flash circuits.
For engineers reviewing the LM3410XMYE/NOPB datasheet, LM3410XMYE/NOPB pinout, LM3410XMYE/NOPB application, or LM3410XMYE/NOPB equivalent, key selection criteria include switching frequency (1.6 MHz), internal compensation, thermal shutdown (165°C), cycle-by-cycle current limit (2.8 A typical), and AEC-Q100 Grade 1 qualification for –40°C to 125°C ambient operation.
Technical Context
The LM3410XMYE/NOPB implements current-mode PWM control with fixed 1.6-MHz oscillator, internal soft-start, and cycle-by-cycle overcurrent protection. Its feedback loop regulates LED current by comparing voltage across an external RSET to a precise 190-mV internal reference, enabling stable constant-current operation independent of LED forward voltage variation.
It supports both boost and SEPIC topologies with internal 170-mΩ NMOS switch and integrated thermal shutdown (trip at 165°C, hysteresis ~15°C). DIM pin accepts 0–100% duty-cycle PWM signals (1 Hz–25 kHz) for analog-equivalent brightness control without external FETs or level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 1.6 MHz - enables use of sub-2.2-µH inductors and 0.47-µF ceramic output capacitors, minimizing board area. |
| Feedback Reference Voltage | 190 mV ±12 mV - sets LED current via ILED = 0.19 V / RSET; tight tolerance ensures accurate current regulation across temperature. |
| Internal Switch RDS(on) | 170 mΩ (typ) - limits conduction loss at 2.8-A peak switch current; supports >88% efficiency in typical boost configurations. |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion (2.7–4.5 V) and 3.3-V/5-V rail systems without external regulators. |
| Output Voltage Range | 3 V to 24 V - supports series strings of up to 6 white LEDs (VF ≈ 3.5 V) or 8 red LEDs (VF ≈ 2.2 V) with margin. |
| Thermal Shutdown Threshold | 165°C (trip), ~150°C (release) - protects against sustained overload or poor PCB thermal design without latch-up. |
| Shutdown Current | 80 nA - enables ultra-low-power standby in battery-powered devices such as portable medical displays or wearables. |
Pinout & Package
LM3410XMYE/NOPB is housed in a thermally enhanced 6-pin WSON package (3.0 mm × 3.0 mm, 0.8-mm height) with exposed die attach pad (DAP) connected to PGND/AGND for low-thermal-resistance PCB mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Switch node output | Drives inductor in boost/SEPIC; swings from GND to VOUT + VF(D1); requires low-inductance routing to minimize EMI. |
| 2 - GND | Signal ground | Reference for FB and DIM; place bottom resistor of feedback divider adjacent to this pin to reduce noise coupling. |
| 3 - FB | Current-sense feedback input | Connects to RSET to GND; senses 190-mV drop to regulate ILED; high-impedance (≤1 µA bias) minimizes divider error. |
| 4 - DIM | PWM dimming/shutdown control | Logic-high (>1.8 V) enables operation; 0–100% PWM duty cycle directly controls average LED current; must not float or exceed VIN + 0.3 V. |
| 5 - VIN | Power supply input | Supplies internal circuitry and switch driver; requires local 2.2–22-µF ceramic bypass capacitor near pin. |
| DAP | Die attach pad (PGND/AGND) | Thermal and electrical ground; must be soldered to PCB ground plane with ≥4 vias (0.3-mm diameter) for RθJA = 55.3°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (–40°C to 125°C), HBM ±2 kV, CDM ±1 kV - suitable for instrument cluster and center-stack LED lighting. |
| Internal compensation | Eliminates need for external compensation network; reduces BOM count and layout sensitivity while maintaining stability across 2.7–5.5 V input and 3–24 V output ranges. |
| 1.6-MHz fixed-frequency operation | Enables <1.0-mm-height inductor selection and avoids AM radio band interference; supports compact, low-profile lighting modules. |
| PWM dimming interface | Direct 0–100% duty-cycle control on DIM pin - no external transistor or level shifter required; supports flicker-free dimming down to 1 Hz. |
| Cycle-by-cycle current limiting | Protects internal NMOS during startup, short-circuit, or inductor saturation; limits peak switch current to 2.1–2.8 A depending on temperature. |
Applications
| Automotive Interior Lighting | Portable Medical Display Backlight |

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 |
|---|---|---|---|
| LM3410YMYE/NOPB | 525-kHz switching frequency; higher RDS(on) (190 mΩ WSON); lower quiescent current (3.4–7 mA vs. 7–11 mA). | Better suited for cost-sensitive, low-EMI designs where larger inductors/capacitors are acceptable; less optimal for space-constrained flash drivers. | Select when board area is less critical than EMI filtering complexity or when driving fewer LEDs at lower currents. |
| TPS61165DRVR | 1.2-MHz fixed frequency; integrated 2-A switch; no internal compensation; requires external RC compensation network. | Offers higher output voltage (up to 38 V) but lacks AEC-Q100 qualification and thermal shutdown hysteresis detail; wider input range (2.7–6 V). | Choose for non-automotive applications needing >24 V output or tighter output voltage regulation; verify compensation stability per layout. |
Compared with LM3410XMYE/NOPB, LM3410YMYE/NOPB trades higher board area for lower EMI and reduced quiescent current, while TPS61165DRVR provides greater output voltage headroom at the cost of added compensation design effort and no automotive qualification.

FAQ
What is the maximum LED string voltage supported by the LM3410XMYE/NOPB?
The LM3410XMYE/NOPB supports output voltages up to 24 V, as specified in its recommended operating conditions. This allows driving series strings of up to six white LEDs (assuming ~3.5 V VF each) or eight red LEDs (~2.2 V VF), provided the total forward voltage plus 190 mV feedback drop remains below 24 V. The actual limit depends on input voltage, efficiency, and thermal design - always verify with worst-case VF and temperature data from the LED datasheet.
Does the LM3410XMYE/NOPB require external compensation components?
No, the LM3410XMYE/NOPB features fully internal compensation, eliminating the need for external RC networks or type-II/type-III compensators. This simplifies design, reduces BOM count, and improves layout insensitivity - confirmed in TI's SNVS541H datasheet Section 7.1 and Figure 11 functional block diagram. Stability is guaranteed across its full operating range when using recommended external components (inductor, input/output capacitors, diode).
How does PWM dimming work on the LM3410XMYE/NOPB DIM pin?
The DIM pin on the LM3410XMYE/NOPB accepts a logic-level PWM signal (0–100% duty cycle, 1 Hz–25 kHz) to directly modulate average LED current. When DIM is high, the device operates normally; when low, it shuts down the internal switch. No external FET or level shifter is needed - the pin sinks only 100 nA and tolerates voltages up to VIN + 0.3 V. For flicker-free dimming at low light levels, TI recommends 200 Hz–1 kHz frequencies.
Is the LM3410XMYE/NOPB qualified for automotive use?
Yes, the LM3410XMYE/NOPB is AEC-Q100 qualified (Grade 1) for automotive applications, with validated performance from –40°C to +125°C ambient temperature, HBM ±2 kV ESD rating, and CDM ±1 kV ESD rating. It meets TI's automotive reliability standards and is listed in the LM3410-Q1 product variant documentation - making it suitable for instrument clusters, center-stack lighting, and other under-hood–adjacent LED systems.
What thermal considerations apply to the LM3410XMYE/NOPB WSON package?
The LM3410XMYE/NOPB in 6-pin WSON (NGG) has RθJA = 55.3°C/W with proper PCB layout: the exposed DAP must be soldered to a solid ground plane using ≥4 thermal vias (0.3-mm diameter), and copper area should extend beyond the package outline. Thermal shutdown activates at 165°C junction temperature, releasing at ~150°C. For continuous 2.8-A peak operation, ensure board-level power dissipation stays within derated limits per Section 6.4 of the datasheet.
