The LM3410 and LM3410-Q1 constant current LED driver are a monolithic, high frequency, PWM DC-DC converter, available in 6-pin WSON, 8-pin MSOP-PowerPad™, and 5-pin SOT-23 packages. With a minimum of external components the LM3410 and LM3410-Q1 are easy to use. It can drive 2.8-A (typical) peak currents with an internal 170-mΩ NMOS switch. Switching frequency is internally set to either 525 kHz or 1.6 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 and LM3410-Q1 use current-mode control and internal compensation to provide high-performance over a wide range of operating conditions. Additional features include PWM dimming, cycle-by-cycle current limit, and thermal shutdown.

Hardware development


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 190mA. The circuit can accept an input voltage of 3.3V-5.5V. The switching frequency of the LM3410X converter is 1.6MHz allowing (...)


Operating Conditions

  • VIN = 3.3V to 5.5V
  • VOUT =˜  VF x 4 + VFB =˜ 2.8V x 4 + 0.190V =˜ 11.4V
  • ILED =˜ 190 mA



The Evaluation Board included in this shipment converts 2.7V to 5.5V input, and illuminates four 50mA LEDs in series using the LM3410X 1.6MHz LED driver switching converter.


The demo board included in this shipment converts 2.7V to 5.5V input, and illuminates a 320 mA HB/OLED using the LM3410X 1.6MHz LED driver switching converter. 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 the demo (...)
