LM3497MX/NOPB Integrated Circuits (ICs)

The LM3497MX/NOPB is a high efficiency LED driver IC developed by Texas Instruments, making a perfect choice for LED driver applications requiring high efficiency and excellent thermal performance. Unlike traditional LED drivers that lose power in the form of heat, this highly efficient device is able to provide high power at a reduced power loss, thus making it an ideal choice for applications that require low thermal dissipation and high power output. It is also suitable for automotive and high-power industrial applications.

The LM3497MX/NOPB is a fully-integrated driver, combining the functionality of a visible LED driver, a current (brightness) regulator, and an LED pre-drive circuit. The LED pre-drive circuit is used to address the slow LED turn-on/off issues inherent in high-power LEDs. This feature ensures fast and accurate control of the LED brightness or current, allowing for improved brightness control and energy efficiency. The driver is also designed with a digital dimming interface, providing compatibility with various TRIAC and PWM dimmers found in automotive and residential applications.

In order to provide high efficiency and excellent thermal performance along with deep dimming flexibility, the LM3497MX/NOPB has been enhanced with Smart Dimming, which includes a Patent-pending flicker free dimming algorithm and a flexible dimming table for easily programming the dimming range. Smart Dimming also allows the user to adjust the dimming operation to match the specific requirements of different applications.

Besides the Smart Dimming features, the unique features of the LM2497MX/NOPB includes a wide dimming range of 0% to 100%, adjustable LED current up to 1.5A, adjustable LED current regulation, and adjustable LED voltage regulation. It also has a comprehensive protection feature, capable of detecting over-voltage and under-voltage conditions, over-temperature conditions and LED fault conditions. The LM3497MX/NOPB is designed to operate with both single-ended and double-ended LED configurations.

The LM3497MX/NOPB is targeted towards applications in both industrial and automotive lighting, such as high-bay lighting, cove lighting, accent lighting and tunnel lighting systems, automotive headlight and dashboard illumination. The device is available for both Automotive AEC-Q100 and industrial applications.

In summary, the LM3497MX/NOPB is a highly efficient LED driver IC from Texas Instruments, making an excellent choice for applications requiring high efficiency and excellent thermal performance. Its unique features include Smart Dimming, adjustable LED current and voltage regulation and comprehensive protection features, making it suitable for both high-power industrial and automotive applications.
