National Semiconductor - offers a broad portfolio of PowerWise® energy-efficient power management ICs that provide constant current for driving both low-power and high-brightness LEDs. Its family of high-brightness LED drivers power 1W-to-5W high-brightness LEDs found in automotive, indoor, outdoor, and other general illumination applications. These LED drivers provide a wide input voltage range, constant current to regulate the LED brightness, and low feedback voltage to minimize power dissipation. Online tools such as reference designs, application notes, and its WEBENCH® LED Designer online tool allow for quick and easy selection, and simulation of a complete LED and LED driver solution.

LM3450: LED Driver with Active PFC and Phase Dimming Decoder

National Semiconductor - LM3450 LED DriverNational Semiconductor's LM3450 is a power factor controller (PFC) with separate phase dimming decoder. The PFC regulates an accurate output voltage while maintaining excellent power factor at the input. The phase dimming decoder interprets the phase angle and remaps it to a 500Hz PWM output. This combination of features is ideal for implementing a dimmable off-line LED driver for 10-100W loads.
