The LM3450/50A is a power factor controller (PFC) with separate phase dimming decoder.

The input-output mapping is programmable for design flexibility, while a dynamic filter and variable sampling rate provide smooth uniform dimming. A dynamic hold circuit ensures that the phase dimmer angle is decoded properly while minimizing extra power loss. The LM3450A is identical to the LM3450 with the exception of one circuit operation. The dynamic hold current is sampled in the LM3450 while it continuously operates in the LM3450A. This difference between the two devices defines the suita.
