The LM3410 constant current LED driver is a monolithic, high frequency, PWM step-up DC/DC converter in 5-pin SOT23, 6-pin LLP, & 8-pin eMSOP packages. With a minimum of external components the LM3410 is easy to use. It can drive 2.5A typical peak currents with an internal 160m NMOS switch. Switching frequency is internally set to either 525kHz or 1.60MHz, allowing 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. External shutdown is included, featuring an ultra-low stand-by current of 80nA. The LM3410 utilizes current-mode control and internal compensation to provide high-performance over a wide range of operating conditions. Additional features include dimming, pulse-by-pulse current limit, and thermal shutdown.
