KP1272FC
KP1272FC Low Harmonic, High Power Factor Buck LED Driver Power Switch KP1272FC is a highly integrated constant current LED power switch. The chip adopts quasi-resonant operation mode and active power factor correction control technology to achieve high power factor, low harmonic distortion, and high efficiency. KP1272FC integrates a high-voltage 500V power MOSFET, a 600V ultra-fast recovery diode, an 800V rectifier bridge, and a high-voltage power supply circuit, simplifying system design and production costs. The chip, through its unique constant current control algorithm, can achieve high-precision constant current output, with excellent line and load regulation performance. KP1272FC 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-circuit and short-circuit protection, etc.
