KP1326
KP1326 Isolated, high PF constant current LED controller with input over/under voltage and OTP grading functions KP1326 is a highly integrated constant current LED power controller. The chip adopts a primary feedback quasi-resonant working mode, and with active power factor correction control technology, it can meet the performance requirements of high power factor, low harmonic distortion, and high efficiency. KP1326 integrates high-precision inductor current sampling technology and a high-precision current comparator reference threshold voltage, and integrates line voltage compensation and load voltage compensation technology, making the drive system have good constant current output characteristics. KP1326 integrates complete protection functions to ensure the safe and reliable operation of the system, such as: VDD undervoltage protection function (UVLO), cycle-by-cycle current limit (OCP), abnormal overcurrent protection (AOCP), adjustable overtemperature protection (OTP), output overvoltage protection (OVP), LED open and short circuit protection, input voltage overvoltage (LOVP), undervoltage protection (LBOP), etc.
