KP1511X series
KP1511X High-performance, critical mode boost PFC constant voltage power switch The KP1511X is a highly integrated boost PFC constant voltage power switch. The chip uses a quasi-resonant operating mode and active power factor correction control technology to meet the requirements of high power factor, ultra-low harmonic distortion, and high efficiency. The KP1511X integrates demagnetization signal detection technology, as well as a high-voltage start-up power supply circuit and a high-voltage MOSFET. It does not require an auxiliary winding for demagnetization and power supply detection, and only requires a few external components, greatly simplifying system design and production costs. The KP1511X 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), and output undervoltage protection (UVP).
