Visible and infrared light-emitting diodes (LEDs) have a wide range of applications, from general illumination to fiber-optic communications and sensing. To meet the increasing efficiency, brightness, and color requirements of the most modern applications, an LED-driver integrated circuit (IC) is needed for efficient, precise, and fast control of current delivered to the LEDs during operation. The Texas Instruments TLC5960DA is a solution for such applications, providing a boost topology driver with integrated high-side and low-side load switches.

The TLC5960DA is a versatile device that can be used in a broad variety of applications. It is designed to control a wide range of LEDs, including standard LEDs, multicolor LEDs, and high power LEDs. It can be used to control individual strings of LEDs or multiple strings of LEDs in a parallel configuration. The TLC5960DA can also be used to control clusters of LEDs in series. The load switches integrated in the device can be used to precisely control the current delivered to the LEDs, reducing power consumption and extending the lifetime of the LED.

The TLC5960DA also includes a pulse width modulation (PWM) control with variable period and variable-duty-cycle functionality. The PWM can be used to control the LED current for light dimming, enabling precise LED brightness control. The device is also capable of providing high frequency, low ripple current regulation, providing precision control of current during operation.

The TLC5960DA operates in pulse frequency modulation (PFM) mode to minimize power dissipation during the non-operational phase. The device also integrates over-temperature protection, under-voltage lockout, and current limitation to protect the LED device and ensure reliable operation. The TLC5960DA is capable of operating at input voltages ranging from 3V to 28V and its output couples directly with LED anodes and cathodes.

The TLC5960DA is a cost-effective solution for LED lighting applications. Its integrated load switches and PWM control enables precise and efficient control of power delivered to the LEDs, extending their lifetime and increasing operating efficiency. Its versatility makes it an ideal solution for a range of visible and infrared LED lighting applications.
