TLC5970RHPT Description

Short technical summary and product information.

The Texas Instruments TLC5970RHPT is a versatile 3-channel, constant-current sink driver designed for LED applications. It integrates a buck DC/DC converter to improve system efficiency and reduce current draw. Each channel provides individually adjustable currents up to 150mA, with 4096 PWM grayscale (GS) steps and 128 constant-current sink steps for dot correction (DC).

 

This device supports global brightness control (BC) and features a differential signal interface for long-distance cascading and auto data refresh. The TLC5970RHPT operates with an input voltage up to 36V and an LED supply voltage up to 17V. It is housed in a 28-QFN exposed pad package suitable for surface mounting.

 

Key electrical characteristics include a data transfer rate of 20 MHz and an operating temperature range of -40°C to 85°C. The integrated EEPROM allows for storage of dot correction data. The device also includes thermal shutdown protection.
