KP116X Series
KP116X Non-isolated, buck-boost active power factor correction LED power switch The KP116X series is a highly integrated constant current LED power switch. The chip uses a quasi-resonant operating mode and adopts active power factor correction control technology to meet the requirements of high power factor, low harmonic distortion, and high efficiency. The KP116X integrates a high-voltage 650V power MOSFET and high-voltage startup and high-voltage power supply circuits, simplifying system design and reducing production costs. By performing full-cycle sampling of the inductor current during the freewheeling period, the chip can achieve ultra-high precision constant current output, and the output line voltage and load regulation performance are excellent. The KP116X 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), LED open and short circuit protection, etc.
