XT2111 Overview
XT2111 is a high-current LED control chip. The chip uses DC-DC control mode , frequency is 500KHz, the chip has wide operating voltage range , the LED current is set by an external resistor, internal to provide an accurate reference to ensure the accuracy of LED current. When the input voltage is above a set value, the chip enters the protection mode at the same time turn off the output.
