Regardless of type, size, or power, all LEDs work best when driven with a constant current since LED color changes with small variations to driving current. LEDs often support varying system voltages and forward voltages, which can further cause variations in LED brightness and color. National’s LED drivers provide the benefit of constant current to single LEDs or arrays of LEDs, enabling color and brightness matching over a wide temperature range.
High-brightness LEDs can require more than 1W of power, making thermal management and drive circuitry an important design consideration. Improper thermal management can significantly degrade the lifetime and performance of the LEDs. Along with temperature sensors, National Semiconductor’s LED drivers offer thermal protection and management to improve the performance of the LEDs in a variety of applications.
