3-Channel , 12-Bit PWM LED Driver W/ Buck DC-DC Converter And Differential Signal Interface

The TLC5970 is a three-channel, constant-current sink driver with a buck DC/DC converter and a differential signal Interface Each channel has individually adjustable currents with 4096 PWM grayscale (GS) steps and 128 constant-current sink steps for dot correction (DC). The dot correction adjusts the brightness variations between LEDs The DC data CAN be stored in the internal EEPROM Also, current through all three channels CAN be controlled by global brightness control (BC) data with 128 steps. GS control, DC, and BC are accessible via a differential signal Interface The maximum current value for each channel is set by a single external resistor. The TLC5970 contains a DC/DC buck converter. The DC/DC converter improves system efficiency, reduces system level currents, and allows thinner gauge wiring by optimizing the LED anode voltage to keep the LED cathode voltage to 1 V. The TLC5970 proivdes overtemperature protection by turning all output drivers off when the IC temperature is too high (exceeds +138°C). By Texas Instruments
