KP1234
KP1234 Boost-type Active Power Factor Correction LED Power Switch KP1234 is a highly integrated boost-type LED constant current power switch. The chip adopts a quasi-resonant operating mode, and with active power factor correction control technology, it can meet the requirements of high power factor, ultra-low harmonic distortion, and high efficiency. KP1234 integrates demagnetization signal detection technology, and integrates high-voltage startup and power supply circuits. It does not require auxiliary winding detection demagnetization and power supply, simplifying system design and 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. KP1234 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.
