Product details
Overview
LM3410XMF/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, supports 2.8-A peak switch current, and targets handheld LED backlight and automotive HB-LED applications.
For engineers reviewing the LM3410XMF/NOPB datasheet, LM3410XMF/NOPB pinout, LM3410XMF/NOPB application, or LM3410XMF/NOPB equivalent, key selection criteria include switching frequency (1.6 MHz), internal compensation, thermal shutdown (165°C), ultra-low shutdown current (80 nA), and SOT-23-5 package compatibility with space-constrained portable designs.
Technical Context
The LM3410XMF/NOPB implements current-mode PWM control with fixed 1.6-MHz oscillator, internal soft-start, and cycle-by-cycle current limiting. Its 190-mV feedback reference sets LED current via external RSET, while the 170-mΩ NMOS switch enables high-efficiency operation up to 88% at typical loads.
It supports both boost and SEPIC topologies, accepts 0–100% PWM dimming on the DIM pin (200 Hz–25 kHz), and features undervoltage lockout (2.65 V rising) and thermal shutdown (165°C). The device uses internal compensation and requires only five external components for basic operation.
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 capacitors for compact PCB layout |
| Feedback reference voltage | 190 mV ±12 mV - sets precise LED current via RSET = 190 mV / ILED; stable over –40°C to 125°C |
| Switch on-resistance | 170 mΩ (typ) - limits conduction loss at 2.8-A peak, supporting >85% efficiency in 5-V input, 12-V output boost |
| Input voltage range | 2.7 V to 5.5 V - matches single-cell Li-ion (2.7–4.5 V) and USB-powered systems without pre-regulation |
| Shutdown quiescent current | 80 nA - enables battery-backed always-on systems with multi-year standby life |
| Thermal shutdown threshold | 165°C - protects die during overload or poor thermal design; auto-recovery at ~150°C |
| Current limit | 2.8 A (typ), 2.1 A (min) - safeguards internal NMOS under short-circuit or cold-start conditions |
Pinout & Package
SOT-23-5 package (3.00 mm × 3.00 mm), thermally enhanced with exposed pad connected to GND; 5-pin configuration optimized for minimal external component count in LED driver applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SW | Switch node output | Drives inductor in boost/SEPIC; swings from GND to VOUT + VF(D1); connects directly to L1 and D1 anode |
| 2: GND | Signal and power ground | Reference for FB, DIM, and internal circuits; must be low-impedance path to minimize noise and ensure regulation accuracy |
| 3: FB | Current-sense feedback input | Monitors voltage across RSET; regulates LED current by maintaining 190 mV at this pin |
| 4: DIM | PWM dimming and enable control | Logic-high (>1.8 V) enables operation; 0–100% duty-cycle PWM controls average LED brightness; max 25 kHz |
| 5: VIN | Power supply input | Supplies internal bias and NMOS gate drive; requires local 2.2–22 µF ceramic bypass capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Internal compensation | Eliminates need for external compensation network-reduces BOM count and layout sensitivity in boost/SEPIC designs |
| 1.6-MHz fixed-frequency PWM | Enables <1 mm² inductor footprint and eliminates audible noise; supports fast transient response in portable displays |
| PWM dimming interface | Direct 0–100% duty-cycle control on DIM pin-no external logic required; compatible with MCU GPIO or dedicated LED controller |
| Thermal shutdown with hysteresis | Shuts down at 165°C and resumes at ~150°C-prevents latch-up and enables self-recovery in thermally constrained enclosures |
| Ultra-low shutdown current | 80 nA maximum-preserves battery capacity in always-on devices such as automotive interior lighting or medical wearables |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3409MM/NOPB | Adjustable 200–2000 kHz frequency; external compensation; higher 3.5-A switch current; requires more external components | Better suited for high-power industrial LED drivers requiring programmable frequency and higher current headroom | Select when design needs >2.8-A peak current or frequency tuning; not drop-in due to different pinout and compensation requirements |
| TPS61165DRVR | 1.2-MHz fixed frequency; integrated 2-A switch; 1.25-V feedback reference; no internal soft-start; smaller WSON-6 package | Optimized for ultra-compact single-LED flash applications; lacks SEPIC support and automotive qualification | Choose for cost-sensitive, space-limited flash drivers where AEC-Q100 compliance and SEPIC topology are not required |

FAQ
What is the switching frequency of the LM3410XMF/NOPB?
The LM3410XMF/NOPB operates at a fixed switching frequency of 1.6 MHz, as confirmed in the Electrical Characteristics table (fSW = 1200–2000 kHz, typical 1600 kHz). This high frequency allows use of miniature surface-mount inductors and ceramic capacitors, reducing solution size and eliminating audible noise in portable applications.
Does the LM3410XMF/NOPB support SEPIC topology?
Yes, the LM3410XMF/NOPB supports SEPIC topology, as explicitly documented in the device description, functional block diagram, and Application and Implementation section (Figure 15). Its current-mode control architecture and internal compensation are validated for both boost and SEPIC configurations with appropriate external component selection.
What is the feedback reference voltage of the LM3410XMF/NOPB?
The LM3410XMF/NOPB has a nominal feedback reference voltage of 190 mV, with a specified range of 178 mV to 202 mV over temperature and process. This value is used to set LED current via RSET = 190 mV / ILED, and is confirmed in Section 6.5 Electrical Characteristics under parameter VFB.
Can the LM3410XMF/NOPB drive multiple LEDs in series?
Yes, the LM3410XMF/NOPB can drive multiple LEDs in series, limited by its 24 V maximum output voltage. For example, with typical white LEDs (VF ≈ 3.3 V), up to seven LEDs may be driven (7 × 3.3 V = 23.1 V), provided the sum of forward voltages plus 190 mV remains below 24 V, as stated in Section 8.1.1.2.
Is the LM3410XMF/NOPB qualified for automotive applications?
The LM3410XMF/NOPB itself is not automotive-qualified; however, the LM3410-Q1 variant is AEC-Q100 Grade 1 qualified (–40°C to 125°C ambient). The LM3410XMF/NOPB shares identical electrical specifications and pinout but lacks automotive test documentation and screening-use LM3410-Q1 for production automotive systems.
