KP1511
KP1511 High-performance, critical mode boost PFC constant voltage controller KP1511 is a highly integrated boost PFC constant voltage controller. The chip adopts a quasi-resonant operating mode, and with active power factor correction control technology, it can meet the requirements of high power factor, ultra-low harmonic distortion, and high efficiency. KP1511 integrates demagnetization signal detection technology, and integrates a 650V high-voltage startup and power supply circuit. It does not require an auxiliary winding to detect demagnetization and power supply, and only requires a few external components, greatly simplifying system design and production costs. KP1511 integrates complete protection functions to ensure safe and reliable operation of the system, such as: VDD undervoltage protection (UVLO), cycle-by-cycle current limit (OCP), overtemperature protection (OTP), output overvoltage protection (OVP), output undervoltage protection (UVP), etc.
