The 1 MHz switching frequency means the PWM dimming ratio is limited by the minimum on-time of the internal switch, not by the switching period — a 100 Hz dimming signal can achieve ratios over 1000:1. The part is listed for general lighting applications and is commonly used in architectural, signage, and automotive exterior lighting where a single high-voltage rail feeds multiple LED strings.","metaTitle":"Texas Instruments LM3402HVMRX/NOPB LED Driver, 500mA, 75V","metaDescription":"Texas Instruments LM3402HVMRX/NOPB DC DC Regulator LED driver, 500mA output, 75V max input, PWM dimming, 1MHz buck topology.
