LED Driver
National SemiconductorRequest Info
Integrating active power factor correction and phase-dimming decoding
across a wide programmable range to provide flicker-free uniform dimming, National
Semiconductor Corp.’ LM3450 LED driver is suitable for use in high-brightness
LED applications. A member of the company’s PowerWise energy-efficient product
family, it is well-suited for high-performance, phase-dimmable 10- to 100-W LED
fixtures. The device integrates hold circuitry to dynamically adjust the current
through the phase dimmer; coupled with a programmable, intelligent dimming decoder,
this ensures smooth, consistent illumination across the full dimming range. The
active power factor correction ensures a high power factor that complies with residential
and commercial Energy Star standards.
