Dimming Led Driver This article describes the LED Driver Best Dimming Performance (LM3450). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: LM3450.

The industry’s best phase-based dimming performance for high-brightnessLEDapplications has arrived. National Semiconductor Corp. has introduced the LM3450LEDdriver which has active power factor correction and phase dimming decoding to provide uniform, flicker-free illumination that covers a broad, programmable dimming range. This driver uses hold circuitry to regulate the current through the phase dimmer, which maintains a smooth and consistent illumination. This controller is able to interpret the phase angle and remaps it to a 500 HzPWMoutput to dim theLEDs. The energy efficient LM3450 complies with residential and commercial Energy Star Standards and can be used with 10 Watt to 100 WattLEDfixtures. For more information, click on the links below.
