NATIONAL SEMICONDUCTOR -LM3410 PowerWise 525kHz/1.6MHz Constant Current Boost SEPIC LED Driver with Internal Compensation handbook
Update: 30 September, 2023
LM3410 is a high frequency, high performance LED driver from Texas Instruments, available in 5 pin SOT23, 6 pin LLP and 8 pin eMSOP packages. It features an internal 170 mΩ NMOS switch that can drive 2.8A typical peak currents. The switching frequency can be internally set to either 525 kHz or 1.60 MHz, allowing for the use of extremely small surface mount inductors and chip capacitors. Even though the operating frequency is high, efficiencies up to 88% are easy to achieve. The LM3410 also features an ultra-low standby current of 80 nA. It utilizes current-mode control and internal compensation to provide high-performance over a wide range of operating conditions. Additional features include dimming, cycle-by-cycle current limit, and thermal shutdown.
