LM3450 Datasheet Led Drivers

Manufacturer: Texas Instruments

Overview: LM3450 .ti. SNVS681D – NOVEMBER 2010 – REVISED MAY 2013 LED Drivers with Active Power Factor Correction and Phase Dimming Decoder Check for Samples:.

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.
