KP107L
KP107L Non-isolated, buck type quasi-resonant LED driver controller KP107L is a highly integrated constant current LED driver controller. The chip adopts a quasi-resonant operating mode and does not require an auxiliary winding to detect demagnetization. At the same time, a high-voltage self-powered circuit is integrated internally, simplifying system design and reducing production costs. The chip integrates high-precision inductor current sampling technology to achieve high-precision constant current output, and the output line voltage and load regulation performance are excellent. KP107L 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), LED short circuit protection, etc.
