TLC5970 Description

Short technical summary and product information.

The TLC5970 from Texas Instruments is a versatile three-channel, constant-current sink driver designed for LED applications. It incorporates a buck DC/DC converter and a differential signal interface, enabling efficient power management.

 

Each of the three channels features individually adjustable currents, providing precise control. This adjustability is achieved through 4096 PWM grayscale (GS) steps and 128 constant-current sink steps for dot correction (DC). The device operates within an input voltage range of 10V to 36V and can provide an output voltage of up to 17V.

 

With a maximum power dissipation of 4.149W and an operating temperature range of -40°C to 85°C, the TLC5970 is suitable for various environmental conditions. Its VQFN package makes it compatible with surface-mount designs.

 

Key electrical characteristics include a maximum output current of 30mA (low level) and 30mA (high level), and a frequency of up to 20MHz. The nominal supply current is 35mA, with a maximum of 150mA.
