KP1274F
KP1274F Low harmonic, high power factor buck LED driver power switch KP1274F is a highly integrated constant current LED power switch. The chip adopts a 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. KP1274F integrates a high-voltage 600V power MOSFET and a high-voltage power supply circuit, simplifying system design and reducing production costs. Through a unique constant current control algorithm, the chip can achieve high-precision constant current output, and the output line voltage and load adjustment rate are excellent. KP1274F integrates complete protection functions to ensure safe and reliable system operation, such as: cycle-by-cycle current limit (OCP), over-temperature protection (OTP), output over-voltage protection (OVP), LED open and short circuit protection, etc.
