KP107Q
KP107Q External overheat regulation protection, buck-type quasi-resonant LED controller KP107Q is a highly integrated constant current LED 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 obtain high-precision constant current output, and the output line voltage and load adjustment rate are excellent. The OTP protection point can be adjusted by external resistor divider. KP107Q integrates complete protection functions to ensure the safe and reliable operation of the system, such as: VDD undervoltage protection (UVLO), cycle-by-cycle current limit (OCP), overtemperature protection (OTP), LED short circuit protection, etc.
