Texas Instruments - Power Factor Controller with Phase Dimming Decoder

Texas Instruments - LM3450 LED DriverThe LM3450 is a power factor controller (PFC) with a separate phase dimming decoder. It is ideal for implementing a dimmable off-line LED driver for 10-100 W loads. The phase dimming decoder interprets the phase angle and remaps it to a 500 Hz PWM output.

Power Integrations - Single-stage PFC with Primary-Side CC, TRIAC-dimmable LED Driver

Power Integrations - LinkSwitch-PHLinkSwitch-PH dramatically simplifies implementation of LED drivers requiring Power Factors greater than 0.9, TRIAC dimming, and high efficiency. This controller introduces a new control technique that provides a very high power factor and eliminates passive circuitry required for power factor correction, optocoupler and secondary current control circuitry.

Evaluation Boards

Evaluation boards include a variety of tools for LED driver evaluation and design reference.


Texas Instruments - LM3450 Evaluation Board

Texas Instruments - LM3450 Evaluation BoardThe 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 decoderinterprets 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.
