KP123
KP123 Boost-type Active Power Factor Correction LED Driver Controller KP123 is a highly integrated boost-type LED driver controller. The chip uses a quasi-resonant operating mode and active power factor correction control technology to meet the requirements of high power factor, ultra-low harmonic distortion, and high efficiency. KP123 integrates demagnetization signal detection technology, and integrates a 650V high-voltage startup and power supply circuit, eliminating the need for auxiliary winding detection demagnetization and power supply, simplifying system design and reducing production costs. The chip integrates high-precision inductor current sampling technology and high-precision output current reference voltage, and integrates line voltage compensation technology, with good constant current output characteristics. KP123 integrates complete protection functions to ensure safe and reliable system operation, such as: VDD undervoltage protection (UVLO), cycle-by-cycle current limit (OCP), overtemperature protection (OTP), output overvoltage protection (OVP), etc.
