High-current LED Controller XT2111 ■ General Description 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. The chip indudes a bendchmark bias, voltage comparator and temperature detection module, XT2111 using thermally enhanced 8-pin small outline package SOP-8. ■ Applications  T6 LED Flahlight  LED stage lights ■ Package  SOP-8 ■ Features  Wide Input Supply Range: 6.
