How it works:
The chip contains a constant current generating circuit, which can set the output constant current value through the external resistor. The switch time of the output channel can be controlled through the enable side of the chip, and the switching frequency is up to one megahertz (1MHz). The current output response is extremely fast, supporting applications with high color level changes and high picture refresh rate. Built-in open circuit detection, overheat outage, and overcurrent protection greatly improve the reliability of the application system.
