Product details
Overview
LM3410YMYE/NOPB from Texas Instruments is a constant-current, 525-kHz PWM boost/SEPIC LED driver IC with internal 170-mΩ NMOS switch, 190-mV feedback reference, and integrated compensation. 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 LM3410YMYE/NOPB datasheet, LM3410YMYE/NOPB pinout, LM3410YMYE/NOPB application, or LM3410YMYE/NOPB equivalent, key selection criteria include switching frequency (525 kHz), thermal shutdown threshold (165°C), dimming interface compatibility (0–25 kHz PWM), and WSON-6 package thermal performance (RθJA = 55.3°C/W).
Technical Context
The LM3410YMYE/NOPB implements current-mode PWM control with internal slope compensation and fixed 525-kHz oscillator. Its error amplifier compares FB voltage against 190-mV reference to adjust duty cycle, while cycle-by-cycle current limiting protects the 170-mΩ NMOS switch at 2.8-A typical peak current.
It supports both boost and SEPIC topologies using minimal external components: single inductor (boost) or coupled inductors (SEPIC), Schottky diode, input/output ceramic capacitors, and FB sense resistor. Shutdown is controlled via DIM pin with 80-nA quiescent current and 0.4-V enable threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching frequency | 525 kHz - enables use of sub-2.2-µH inductors and 0.47-µF ceramic output capacitors for compact layout |
| Feedback reference voltage | 190 mV ±12 mV - sets LED current precision via RSET = 190 mV / ILED; low drift supports stable brightness over temperature |
| Input voltage range | 2.7 V to 5.5 V - compatible with single-cell Li-ion (2.7–4.2 V) and USB-powered systems without LDO pre-regulation |
| Output voltage capability | Up to 24 V - supports series strings of 6–8 white LEDs (3.2–3.6 V each) or HB LED arrays in automotive cabin lighting |
| Internal switch RDS(on) | 170 mΩ (typical) - limits conduction loss to <150 mW at 1.5-A load, enabling >85% efficiency in 5-V-to-12-V boost configurations |
| Thermal shutdown threshold | 165°C - protects die during sustained overload or poor PCB thermal design; auto-recovery at ~150°C junction temperature |
| Shutdown quiescent current | 80 nA - allows battery-backed systems to maintain >1-year shelf life without significant drain |
Pinout & Package
LM3410YMYE/NOPB uses the 6-pin WSON package (3.00 mm × 3.00 mm, 0.5-mm pitch) with exposed thermal pad (DAP) connected to PGND for enhanced heat dissipation. The DAP must be soldered to ≥4 vias tied to internal ground plane.
| 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 VIN | Power supply input | Supplies gate drive and bias circuitry; bypass with 4.7–10 µF ceramic capacitor placed within 3 mm of pin |
| 3 FB | Current-sense feedback input | Connects to bottom of RSET; senses voltage drop across RSET to regulate LED current; sensitive to noise - route away from SW |
| 4 DIM | PWM dimming/shutdown control | Logic-level input: 0 V = shutdown (80 nA IQ), ≥1.8 V = enabled; accepts 1 Hz–25 kHz PWM for analog-equivalent brightness control |
| 5 GND | Signal ground | Reference for FB and DIM; place RSET and DIM pull-down resistor close to this pin to reduce noise coupling |
| 6 DAP | Thermal & power ground | Exposed pad - must be soldered and connected to PGND plane with ≥4 thermal vias (0.3-mm diameter) for RθJA = 55.3°C/W |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 170-mΩ NMOS switch | Eliminates external MOSFET and gate driver, reducing BOM count and PCB area by >30% vs discrete solutions |
| Internal compensation network | Removes need for external compensation components - only RSET, inductor, diode, and two ceramics required for full operation |
| 190-mV precision feedback reference | Enables ±3% LED current accuracy over –40°C to 125°C without calibration; supports RSET values from 0.1 Ω to 10 Ω |
| 525-kHz fixed-frequency PWM | Permits use of 1.0–2.2-µH shielded power inductors (e.g., Coilcraft XAL5030) and avoids AM radio band interference |
| Thermal shutdown with hysteresis | Prevents permanent damage during transient overloads; 15°C hysteresis ensures stable restart after cooling |

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 |
|---|---|---|---|
| LM3410XMYE/NOPB | 1.6-MHz switching frequency; higher RDS(on) (190 mΩ WSON); reduced max duty cycle (88–92%) | Better suited for ultra-compact layouts needing <1-µH inductors; lower efficiency at high output voltages due to increased switching loss | Select when board space is constrained and input-to-output voltage ratio is low (e.g., 3.3-V to 5-V boost) |
| TPS61165DRVR | 2.2-MHz fixed frequency; 1.8-A switch limit; 200-mV reference; no internal compensation (requires external RC) | Higher frequency enables smaller passives but demands careful loop compensation; lacks AEC-Q100 qualification | Choose for consumer portable devices where automotive qualification is unnecessary and higher switching frequency is acceptable |
Compared with LM3410YMYE/NOPB, LM3410XMYE/NOPB trades efficiency for smaller magnetics, while TPS61165DRVR offers higher frequency at the cost of design complexity and no automotive qualification - making LM3410YMYE/NOPB optimal for thermally demanding, safety-conscious, space-constrained LED systems.

FAQ
What is the maximum LED string voltage supported by LM3410YMYE/NOPB?
The LM3410YMYE/NOPB supports output voltages up to 24 V, as specified in its absolute maximum ratings for the SW pin. This allows driving series strings of up to eight standard white LEDs (3.2–3.6 V VF each) or six high-VF red/amber LEDs. Operation above 24 V risks permanent damage and is not supported.
Does LM3410YMYE/NOPB require external compensation components?
No, the LM3410YMYE/NOPB features internal compensation, eliminating the need for external RC networks. Only five external components are required for basic operation: input capacitor, output capacitor, inductor, Schottky diode, and FB sense resistor. This simplifies design and improves production yield.
Can LM3410YMYE/NOPB be used in SEPIC topology?
Yes, the LM3410YMYE/NOPB supports SEPIC configuration per TI's application documentation. It regulates LED current identically in SEPIC mode, enabling output voltages both above and below input - ideal for single-cell Li-ion (2.7–4.5 V) powering 3.3-V or 5-V OLED bias rails without buck-boost mode transitions.
What is the purpose of the DAP pin on LM3410YMYE/NOPB?
The DAP (Die Attach Pad) on LM3410YMYE/NOPB is an exposed thermal pad that serves as the primary thermal and electrical connection to PGND. It must be soldered to a dedicated PCB ground plane with at least four 0.3-mm-diameter vias to achieve the rated RθJA of 55.3°C/W and prevent thermal shutdown under continuous 1.2-A load.
How does the DIM pin function in LM3410YMYE/NOPB?
The DIM pin on LM3410YMYE/NOPB serves dual functions: logic-level enable/disable (0 V = shutdown, ≥1.8 V = active) and analog-equivalent PWM dimming input (0–100% duty cycle, 1 Hz–25 kHz). It draws only 100 nA, allowing direct MCU GPIO control without level-shifting or additional drivers.
