The SEPIC capability is the key differentiator here: it can regulate an output voltage above, below, or equal to the input voltage using a single inductor and a coupling capacitor. For a backlight driver running from a Li-Ion battery (3.0-4.2 V), the LED string voltage may be 9 V (three series LEDs) or 6 V (two series LEDs), and the battery voltage crosses the LED string voltage during discharge. A standard boost converter would drop out of regulation when the battery voltage exceeds the LED string voltage; the SEPIC topology keeps the LEDs lit across the full battery range. ## 2.8 A switch current — the power-stage ceiling, not the LED current The 2.8 A rating is the peak current the internal N-channel switch can handle, not the continuous LED current. The actual LED current is set by the external sense resistor and the inductor ripple current. ## PWM dimming — logic-level control, not analog Dimming is controlled by a PWM signal applied to the shutdown or feedback pin, not by an analog voltage on a dedicated dimming pin. The PWM frequency should be above 200 Hz to avoid visible flicker, and the minimum on-time of the internal switch (typically 100-200 ns) sets the minimum dimming pulse width. At a 1.6 MHz switching frequency, the PWM dimming ratio is limited by the switching cycle time — a 1% duty cycle at 200 Hz PWM is 50 µs, which is 80 switching cycles, enough for the inductor current to settle. The output voltage range of 3 V to 24 V means the part can drive up to six white LEDs in series at 3.3 V each, or a single high-voltage LED string. ## Temperature grade and package — board-fit checklist The operating junction temperature range is -40°C to 125°C, which covers automotive under-hood and industrial environments. The recommended land pattern from TI includes a 2.2x2.2 mm pad with four thermal vias (0.3 mm diameter) to the ground plane. The narrow leads (0.4 mm pitch) require a solder paste stencil thickness of 0.125 mm to avoid bridging. The part is ROHS3 compliant (no RoHS exemptions), so it is fully lead-free and suitable for EU-market products without an exemption expiry date. ## Sourcing and compliance documentation Texas Instruments provides the LM3410XSD/NOPB with full compliance documentation: ROHS3 certification (no exemption-based RoHS), REACH compliance data, and the standard TI product change notification (PCN) process.","metaTitle":"Texas Instruments LM3410XSD/NOPB LED Driver, 2.8A Switch","metaDescription":"Texas Instruments LM3410XSD/NOPB DC-DC regulator, SEPIC/boost topology, 2.8A switch, 1.6MHz, PWM dimming, 6-WSON.

The TLC5940 is a 16-channel linear LED driver with shift-register control, 120 mA per channel, and a 30 MHz serial interface. The LM3410XSD/NOPB is a single-channel switching regulator (SEPIC/boost) with a 2.8 A switch and PWM dimming. They serve different power stages: the LM3410 drives the LED string current directly from a battery; the TLC5940 sinks current from a pre-regulated supply. They are not pin-compatible and cannot be swapped on the same PCB without a complete redesign of the power stage and control interface"}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3410XSD-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3410XSD-NOPB when reusing this data.
