KP1061CSPA

The KP106XC series are highly integrated constant-current LED power switches. The chips employ a quasi-resonant operating mode combined with active power factor correction control technology to achieve high power factor, low harmonic distortion, and high efficiency. The KP106XC integrates a high-voltage 500V power MOSFET along with high-voltage startup and power supply circuits, simplifying system design and reducing production costs. By sampling the inductor current over the full cycle, the chip delivers ultra-high accuracy constant-current output with excellent line voltage and load regulation performance. The KP106XC incorporates comprehensive protection features to ensure safe and reliable system operation, including: VDD undervoltage lockout (UVLO), cycle-by-cycle current limiting (OCP), overtemperature protection (OTP), output overvoltage protection (OVP), and LED open-circuit and short-circuit protection. Package type: SOP-7
