KP18108
KP18108 High PF High Efficiency Flicker-Free Linear Constant Current Driver KP18108 is a high PF, high efficiency linear constant current LED driver chip. It adopts linear constant current technology and sets the LED string current precisely through an external resistor. The chip meets the requirements of IEC-61000-3-2:2018. The system has excellent linear regulation rate, and the peripheral is simplified without magnetic components, meeting EMI requirements, achieving small size and long life, and greatly reducing the system cost. KP18108 integrates OTP function. When the chip temperature is too high, the system will reduce the output current to ensure the safety and reliability of the system.
