LM3447MT Description

Short technical summary and product information.

The Texas Instruments LM3447MT is an active phase dimmable, primary side power regulated, PFC Flyback controller designed for LED lighting applications. It operates with an AC/DC input voltage range from 7.5V to 17.5V and can provide an output voltage up to 60V with a maximum output current of 2A.

 

Key features include adjustable switch frequency, soft switching, and thermal shutdown. The device supports both forward and reverse phase dimming methods, offering over 50:1 dimming range. It incorporates Power Factor Correction with low Total Harmonic Distortion and uses primary side control with input voltage feedforward for improved line regulation. The controller operates in fixed frequency discontinuous conduction mode with valley switching for high efficiency and low EMI.

 

This LED driver IC is housed in a TSSOP (PW) package with dimensions of 5 mm x 6.4 mm, covering an area of 32 mm². It includes integrated phase angle decode, efficient TRIAC hold current management, and protection features such as thermal foldback, LED open circuit, and short circuit protection.

 

The LM3447MT is suitable for various illumination applications requiring precise LED power control and dimming.
