LM3450 Datasheet (Texas Instruments)

LM3450, LED Drivers

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 dimm
