Product details
Overview
LM3410XQMF/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 HB LED flash circuits.
For engineers reviewing the LM3410XQMF/NOPB datasheet, LM3410XQMF/NOPB pinout, LM3410XQMF/NOPB application, or LM3410XQMF/NOPB equivalent, key selection criteria include switching frequency (1.6 MHz), thermal shutdown threshold (165°C), cycle-by-cycle current limit (2.8 A typ), internal compensation, and AEC-Q100 Grade 1 qualification for –40°C to 125°C ambient operation.
Technical Context
The LM3410XQMF/NOPB implements current-mode PWM control with fixed 1.6-MHz oscillator, enabling stable regulation of LED current independent of input/output voltage variations. Its internal 170-mΩ NMOS switch and 190-mV precision reference allow accurate current setting via single external resistor at FB pin.
It supports both boost and SEPIC topologies with internal soft-start, undervoltage lockout (2.65 V rising), and thermal shutdown (165°C). DIM pin accepts 0–100% duty-cycle PWM signals (1 Hz–25 kHz) for brightness control without analog current scaling.
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 as ILED = 0.19 V / RSET; tolerance directly impacts current accuracy. |
| Switch on-resistance | 170 mΩ (typ) - limits conduction loss at peak switch current; critical for efficiency above 1 A load. |
| Peak switch current limit | 2.8 A (typ), 2.1 A (min) - protects internal FET during startup or overload; defines maximum deliverable LED power. |
| 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. |
| Output voltage range | 3 V to 24 V - supports strings of up to 7 white LEDs (VF ≈ 3.4 V) or 4 red LEDs (VF ≈ 2.2 V) in series. |
| Quiescent current (shutdown) | 80 nA - enables ultra-low-power standby in battery-powered devices with external enable control. |
Pinout & Package
LM3410XQMF/NOPB uses a 6-pin WSON package (3.00 mm × 3.00 mm, 0.5-mm pitch) with exposed thermal pad (DAP) connected to PGND/AGND for enhanced thermal dissipation.
| 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 layout to minimize EMI. |
| 2 VIN | Power supply input | Supplies gate drive and bias circuitry; must be decoupled with ≥2.2 µF MLCC close to pin. |
| 3 FB | Current-sense feedback input | Connects to bottom of RSET; regulates LED current by holding voltage at 190 mV; high-impedance (≤1 µA bias). |
| 4 DIM | PWM dimming/shutdown control | Logic-high (>1.8 V) enables operation; 0–100% PWM duty cycle controls average LED brightness; must not float. |
| 5 GND | Signal ground | Reference for FB and DIM; place RSET and DIM pull-down near this pin; separate from PGND in high-current layouts. |
| DAP | Thermal pad / Power ground | Internally connected to PGND and AGND; requires ≥4 thermal vias to inner-layer GND plane for thermal reliability. |
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-enables use in instrument clusters and cabin lighting. |
| Internal compensation | Eliminates need for external compensation network; reduces BOM count and design iteration time for boost/SEPIC configurations. |
| 1.6-MHz fixed-frequency operation | Permits use of 1.0–2.2 µH shielded inductors and 0.47–2.2 µF X7R/X5R MLCCs-ideal for space-constrained portable designs. |
| 190-mV precision reference | Enables ±6% LED current accuracy over temperature and line (ΔVFB/VIN = 0.06%/V); avoids costly external references. |
| Thermal shutdown (165°C) | Protects against sustained overload or poor heatsinking; auto-recovery at ~150°C junction-no latch-up or manual reset required. |

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 |
|---|---|---|---|
| LM3410YQMF/NOPB | 525-kHz switching frequency; higher RDS(ON) (190 mΩ typ in WSON); lower quiescent current (7 mA vs. 11 mA in active mode) | Better suited for noise-sensitive audio-adjacent layouts; requires larger inductors (≥4.7 µH) and capacitors | Select when EMI filtering priority outweighs board area constraints. |
| TPS61165DRVR | 1.2-MHz fixed frequency; integrated 2-A switch; no internal compensation; requires external RC compensation network | Lacks AEC-Q100 qualification; rated only for industrial temp (–40°C to 85°C); no thermal shutdown | Choose for cost-sensitive consumer electronics where automotive reliability is not required. |

FAQ
What is the recommended inductor value for LM3410XQMF/NOPB in a typical 5-V input, 12-V/350-mA LED boost application?
For LM3410XQMF/NOPB operating at 1.6 MHz with 5 V input and 12 V/350 mA output, TI recommends a 1.5 µH shielded power inductor with ≥2.5 A saturation current. This value balances input ripple (<30% of average), peak switch current margin (2.8 A limit), and physical size-verified in TI's TIDA-00253 reference design. Use ferrite-core MLCC-compatible inductors with low DCR (<80 mΩ) to maintain >85% efficiency.
Does LM3410XQMF/NOPB support analog dimming, or is it PWM-only?
LM3410XQMF/NOPB supports PWM dimming only via the DIM pin; it does not provide analog (DC voltage) dimming capability. The DIM pin accepts logic-level PWM signals from 1 Hz to 25 kHz with 0–100% duty cycle. Attempting to apply a DC voltage between 0.4 V and 1.8 V results in undefined behavior-TI explicitly prohibits analog control per Section 6.5 of the datasheet.
Can LM3410XQMF/NOPB drive LEDs in SEPIC topology, and what external components are required beyond the boost configuration?
Yes, LM3410XQMF/NOPB supports SEPIC topology using the same IC-no firmware or pin changes needed. Beyond standard boost components, add a second inductor (L2), coupling capacitor (C2), and adjust feedback resistor placement. TI's Figure 15 shows L1/L2 equal-value (e.g., 2.2 µH), C2 ≥10 µF ceramic, and C1/C3 ≥2.2 µF. SEPIC allows output voltage regulation both above and below input-essential for Li-ion battery (2.7–4.5 V) powering 3.3 V OLED bias rails.
What is the thermal performance difference between LM3410XQMF/NOPB in WSON versus MSOP-PowerPad packages?
LM3410XQMF/NOPB in WSON (NGG) has RθJA = 55.3°C/W (0 LFPM), while the MSOP-PowerPad (DGN) achieves 53.7°C/W-nearly identical. However, WSON's smaller footprint (3.0 × 3.0 mm vs. 2.9 × 1.6 mm) concentrates heat; its RθJC(bot) is 9.3°C/W versus 6.8°C/W for MSOP, meaning MSOP transfers heat more efficiently to PCB. For >1.5 W dissipation, MSOP is preferred unless board area strictly constrains layout.
How does the 190-mV feedback reference in LM3410XQMF/NOPB impact LED current accuracy across temperature?
The 190-mV reference in LM3410XQMF/NOPB exhibits ±12 mV variation from –40°C to 125°C (spec in Section 6.5), yielding ±6.3% LED current error at extremes if RSET is temperature-stable. Combined with RSET drift (e.g., 100 ppm/°C), total current error reaches ±8% over full range. TI mitigates this via internal trimming-no external calibration needed-and recommends 1% metal-film RSET for best accuracy.
