What are the key features of LM3410YSD?
- Constant-current LED drive via boost and SEPIC topologies supports LED string voltages above, equal to, or below input voltage in a single design
- Integrated heat slug in 6-pin TSOT package improves thermal dissipation, enabling higher LED drive currents without external heatsinks
- 5-segment dimming control via PWM or analog input allows smooth LED brightness adjustment from 0% to 100% duty cycle
What is LM3410YSD used for?
The LM3410YSD is ideal for driving LED backlights in portable displays, handheld devices, and industrial panel indicators where input voltage may be lower or higher than the LED string voltage. Its SEPIC topology enables operation from a single Li-ion cell at 2.7 V to 5 V input while driving white LEDs requiring 3.0 V to 3.6 V forward voltage. The compact 6-pin TSOT package with heat slug suits space-constrained designs in smartphones, tablets, and wearable electronics.

Frequently Asked Questions
What LED driver topologies does LM3410YSD support and what flexibility does this provide?
The LM3410YSD supports both boost and SEPIC topologies, allowing it to drive LED strings with forward voltages above, equal to, or below the input voltage. This makes it suitable for single-cell Li-ion applications from 2.7 V to 4.2 V driving white LEDs at 3.2 V to 3.6 V forward voltage.
How does the integrated heat slug in LM3410YSD's 6-pin TSOT package benefit LED driver designs?
The exposed heat slug on the LM3410YSD's 6-pin TSOT package conducts heat directly to the PCB copper, reducing junction-to-ambient thermal resistance by several degrees Celsius per watt compared to standard TSOT without slug. This allows higher continuous LED drive currents in compact designs without external heatsink components.
For a portable handheld device backlight, how does LM3410YSD maintain constant LED current during battery voltage fluctuation?
The LM3410YSD uses a current-sense feedback loop to regulate LED current regardless of input voltage variation from approximately 2.7 V to 5.5 V. Even as a Li-ion battery discharges from 4.2 V to 2.7 V, the SEPIC topology maintains constant current through LED strings with up to 5 segments, ensuring consistent display brightness over the full battery range.
