LED Drivers & LED Lighting Design

National's industry-leading TRIAC dimmable offline LED driver solution is perfect for any application where an LED driver must interface to a standard triac wall dimmer. National's new TRIAC dimmable LED driver delivers a wide, uniform dimming range free of flicker, best-in-class dimming performance, and high efficiency—all while maintaining ENERGY STAR® power factor requirements in a typical application.

• Application voltage range from 80 VAC to 270 VAC
• Angle detector/decoder enables wide (100:1) full range dimming
• Integrated 300Ω bleeder resistor to ensure proper TRIAC signal decoding
• Patent-Pending control architecture allows for constant ripple current which extends the life of the LEDs
• Scalable output current up to and greater than 1A
• Master/Slave control for uniform dimming across multi-channel applications
• Ideal dimming solution for MR16 & PAR20, PAR25, PAR30, PAR38 LED bulbs
