KP1466XC Series
KP1466XC PWM Dimmable, Buck Type, High Power Factor LED Constant Current Power Switch The KP1466XC is a highly integrated constant current LED power switch. The chip uses a quasi-resonant operating mode and active power factor correction control technology to achieve high power factor, low harmonic distortion, and high efficiency. The KP1466XC integrates a high-voltage 500V power MOSFET and high-voltage power supply circuit, simplifying system design and reducing production costs. Through a unique constant current control algorithm, the chip achieves high-precision constant current output, and exhibits excellent line voltage and load regulation. The KP1466XC also integrates a unique dimming technology that provides high-precision PWM signal dimming. The KP1466XC integrates complete protection functions to ensure safe and reliable system operation, such as: cycle-by-cycle current limiting (OCP), over-temperature protection (OTP), output over-voltage protection (OVP), LED open and short circuit protection, etc.
