National Semiconductor Introduces Industry's First Common-Anode, Current-Mode, High-Brightness LED Driver with PWM Dimming
National Semiconductor Corporation has introduced the industry's first
common-anode, current-mode, high-brightness light-emitting diode (LED) driver with pulse-width modulation (PWM) dimming.
The LM3433, a member of National's PowerWise energy-efficient product family, drives high-power,
high-brightness LEDs in backlighting, projector and solid-state lighting applications.
National's LM3433 LED driver opens the way for high-reliability LEDs to be used in large-screen liquid crystal display (LCD) television (TV) backlighting applications where a common anode approach offers a thermal advantage. In another example, LEDs can be used in today's shrinking ‘pocket projector’ designs for a wider color gamut, higher reliability and longer life expectancy than the ultra-high performance (UHP) lamps used today.
