    • Description

    The LM3410 constant current LED driver is a monolithic, high frequency, PWM 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 2.8A typical peak currents with an internal 170 mΩ NMOS switch. Switching frequency is internally set to either 525 kHz or 1.60 MHz, 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 standby current of 80 nA. The LM3410 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.

    This evaluation board showcases the LM3410X as a boost LED driver. It is designed to drive four, on-board LEDs (VOUT = 11.4V) in series at an average LED current (ILED) of 190 mA. The circuit can accept an input voltage of 3.3V-5.5V. The switching frequency of the LM3410X converter is 1.6MHz allowing the use of small surface mount inductors and chip capacitors. This evaluation board also features the PWM capability of the LM3410 by enabling the user to apply a periodic pulse signal to the DIM terminal of varying duty cycle. This is a 2-layer board using the bottom layer as a ground plane. The above restrictions for the input voltage are valid only for this evaluation board.

    Operating Conditions

    • VIN = 3.3V to 5.5V
    • VOUT =˜  VF x 4 + VFB =˜ 2.8V x 4 + 0.190V =˜ 11.4V

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
