KP1326A
KP1326A Isolated, high PF constant current LED controller with input over/under voltage and OTP grading functions The KP1326A is a highly integrated constant current LED power controller. The chip uses a primary feedback quasi-resonant operating 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. The KP1326A 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. The KP1326A integrates complete protection functions to ensure the safe and reliable operation of the system, such as: VDD undervoltage protection (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.
