National Semiconductor LM3410 Manuals

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.

The LM3410 is a high frequency constant current LED driver from TI. It features a high switching frequency (525kHz or 1.6MHz), low standby current, small package size and high efficiency. LM3410 is suitable for applications such as LED backlight, LiIon backlight OLED and HB LED driver, handheld devices and LED flash driver.
