KP1313X series
KP1313X High-efficiency quasi-resonant, primary constant current LED power switch KP1313X is a high-performance quasi-resonant, primary-side controlled LED power switch that provides high-precision constant current output performance, especially suitable for medium and high-power isolated luminaire power supplies. KP1313X uses a constant current loop to achieve quasi-resonant control, and the valley conduction working mechanism can greatly reduce switching losses, improve efficiency, and improve EMC. The chip integrates line voltage and load voltage constant current compensation to achieve excellent line voltage and load regulation. KP1313X integrates multiple protection functions: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), overtemperature protection (OTP), cycle-by-cycle current limiting protection (OCP), LED open and short circuit protection, etc.
