Its 1 MHz switching frequency lets the designer use a small inductor, which helps keep the total solution footprint tight for space-constrained lamp modules or daytime-running-light boards. The input range of 6 V to 42 V covers the typical automotive battery rail through cold-crank and load-dump transients without requiring an external pre-regulator. ## Temperature range and lighting-grade qualification ## PWM dimming and single-output drive PWM dimming is supported directly, allowing the LED current to be chopped at a user-defined duty cycle for brightness control without shifting the colour temperature. The single output channel delivers a regulated 1 A, which means the LM3404MA/NOPB is a direct fit for a single high-power LED or a small series string, not a multi-channel array driver. Supplied in an 8-pin SOIC package (0.154\" body width, 3.90 mm) for surface-mount assembly, with the supplier device package also designated as 8-SOIC.","metaTitle":"LM3404MA/NOPB LED Driver, DC DC Regulator, 1A, 8-SOIC","metaDescription":"LM3404MA/NOPB is a 1A buck LED driver with PWM dimming, 1 MHz switching, 6V-42V input, -40°C to 125°C.
