TLC5954RTQR is an integrated, configurable LED driver with low voltage drop, low noise RMS LED dimming rate control and LED short circuit protection. It offers up to 16 channels of LED control with a wide range of features, including a wide input voltage range, adjustable rise/fall time, adjustable soft start/stop times, optional boost enable and low battery indication, configurable matching between channels, anti-glare and current limiting, dimmable frequency setting, dimming window control, and pre-programmable dimmer profiles. The TLC5954RTQR is ideal for applications in industrial lighting, automotive lighting, medical lighting and audiovisual lighting.

The TLC5954RTQR is a wide input voltage range configurable, four-channel, constant current, step-down/step-up LED driver that is capable of driving up to 16 independent, programmable-current LEDs up to 4A each. It features 0.8V voltage dropout and is available in a leadless 8 mm x 8 mm package with 14 pins. This device has a wide input voltage range of 2.6V to 18V, making it suitable for use with either 3.3V or 5V regulated power supplies as well as Off-Line/Line-Transformer power supplies. It features high efficiency with total delivered current up to 16A.

The TLC5954RTQR is a PWM dimmable controller which uses an internal step-down/step-up power converter to regulate the LED current. It uses a modulated linear regulator to control the current and voltage to the LEDs. This device allows for a wide range of dimming modes and profiles, including pulse width modulation (PWM), dimming with external PWM signal or analog control, or dimming with pre-programmed dimming profiles. Additionally, the TLC5954RTQR also has adjustable external voltage, current or LED temperature control, as well as LED short circuit protection.

The TLC5954RTQR is designed to provide high efficiency, low noise, and flexibility for LED dimming applications. It is flexible in the fact that the user can configure the current, frequency, PWM duty cycle and rise/fall times, enabling the user to optimize the LED dimming performance for their specific application. It also features an adjustable rise/fall time, allowing the user to set their own dimming profiles according to the application. As a result, the TLC5954RTQR ensures the LEDs are dimmed consistently and without excessive noise. This makes it ideal for applications such as industrial and medical lighting, where noise-free illumination is critical.

The TLC5954RTQR can also be used for audiovisual applications. It has an adjustable dimming frequency and duty cycle, as well as a low duty cycle startup and a low noise frequency mode that can be used with an external low frequency clock signal. This feature allows audio/video applications to dim the LEDs in step with the audio frequency, providing an aesthetically pleasing display.

In summary, the TLC5954RTQR is a highly configurable LED driver that can be used in a variety of lighting and audiovisual applications. It has a wide input voltage range, adjustable voltage, current and LED temperature control, adjustable PWM rise/fall time, adjustable frequency, optional boost enable and low battery indication, and LED short circuit protection. Additionally, it offers a flexible and noise-free dimming solution for applications such as industrial and medical lighting, as well as audiovisual applications.
