KP1325
KP1325 Isolated, single-stage active power factor correction LED driver controller KP1325 is a highly integrated constant current LED power controller. The chip adopts 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. KP1325 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, with good constant current output characteristics. KP1325 integrates complete protection functions to ensure safe and reliable operation of the system, such as: VDD undervoltage protection (UVLO), cycle-by-cycle current limit (OCP), abnormal overcurrent protection (AOCP), overtemperature protection (OTP), output overvoltage protection (OVP), LED open and short circuit protection, etc.
