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.
The LM3410 PowerWise LED driver is a monolithic, high‑frequency PWM DC‑DC converter that provides constant‑current LED drive up to 2.8 A peak. It features internal compensation, ultra‑low standby current, current‑mode control, dimming, cycle‑by‑cycle current limit and thermal shutdown. The device operates from 2.7 V to 5.5 V input and can be configured for 525 kHz or 1.6 MHz switching, allowing the use of very small surface‑mount inductors and capacitors.
Typical applications include LED backlight current sources, OLED/HB LED drivers, handheld devices and LED flash drivers. The LM3410 is offered in three package types—SOT‑23‑5, LLP‑6 and eMSOP‑8—each with a low‑profile footprint for space‑constrained designs.
