KP28162
KP28162 PF>0.7, Floating BUCK Adaptive Constant Voltage Output Power Switch KP2816X is a constant voltage output power switch for dimming and color mixing LED applications. The chip uses a quasi-resonant operating mode and adaptively adjusts the output voltage to meet the voltage requirements of the downstream linear constant current while improving system efficiency. KP2816X integrates a high-voltage 500V power MOSFET and high-voltage startup and power supply circuits, simplifying system design and reducing production costs. The chip has a light-load frequency reduction mode, which can improve the stability of the system operation under light load or no-load conditions, while maintaining high efficiency. KP2816X integrates complete protection functions, including: VDD undervoltage protection (UVLO), output overvoltage protection (OVP), output short-circuit protection (SCP), cycle-by-cycle current limiting (OCP), built-in overtemperature protection, and leading edge blanking (LEB).
