Overview

LM3450 LM3450A LED Drivers with Active Power Factor Correction and Phase Dimming Decoder LM3450 LM3450A June 20, 2011 LED Drivers with Active Power Factor Correction and Phase Dimming Decoder General Description The LM3450/50A is a power factor controller (PFC) with separate phase dimming decoder.
The PFC regulates the output voltage while maintaining excellent power factor.
The phase dimming decoder interprets the phase angle and remaps it to a 500Hz PWM output.
This device is ideal for implementing a dimmable off-line LED driver for 10-100W loads.
The phase dimming decoder has several unique features.
The input-output mapping is programmable for design flexibility, while a dynamic filt...
