LED Driver Integrates Power Factor Correction and Phase Dimming Decoding to Provide Flicker-free, Uniform Dimming

National Semiconductor introduces the LM3492 LED driver, a member of National's PowerWise® energy-efficient product family, with dynamic headroom control, which drives current to two independently dimmable strings of LEDs.  

PowerWise Controller Maximizes System Efficiency, Simplifies Design and Reduces System Cost

Arrow Electronics, Inc. (NYSE:ARW) has teamed with Cree and National Semiconductor Corp. to deliver a reference design for a flicker-free, wide-dimming-range LED driver board.  The new reference design empowers engineers to rapidly develop an LED lighting solution, featuring white LEDs on a programmable board that meets the ENERGY STAR power requirements.

National Semiconductor Corp. today announced a new LED driver with temperature management control and the addition of an online design environment to support it.  The LM3424, a member of National’s PowerWise® energy-efficient product family, drives high-brightness LEDs in a variety of indoor, outdoor and automotive applications.  Supported in National’s WEBENCH® LED Designer, its temperature management control, thermal foldback, enables lighting designers to quickly and easily design a reliable thermal syste

National Semiconductor Corp. today introduced the industry's smallest white light-emitting diode (LED) driver with dynamic display backlight control. The LM3530, a member of National's PowerWise energy-efficient product family, drives up to 11 high-current LEDs in series, illuminating larger displays in portable media devices such as smartphones. The LM3530 is offered in a 12-bump micro SMD package measuring just 1.615 mm x 1.215 mm x 0.425 mm.

National Semiconductor Corp. (NYSE: NSM) Monday introduced the industry's first high-side light-emitting diode (LED) driver that enables dual LED operation for the camera flash function in portable, battery-powered multimedia devices. The LM3554, a member of National's PowerWise(R) energy-efficient product family, drives one or two high-current LEDs for flash applications in handheld devices such as mobile phones, smartphones and portable scanners.

National Semiconductor has introduced a TRIAC dimmable LED driver - the LM3445. The company says the constant-current controller enables uniform dimming of high brightness LEDs, without flicker.
