It is an active power factor correction controller with critical conduction mode, suitable for small and medium power switching power supplies. The multiplier with built-in harmonic optimization can achieve harmonic optimization over a wide range of input voltages and load currents, with extremely low harmonic distortion and a power factor close to 1. Built in comprehensive protection functions: VCC undervoltage protection (UVLO), system output overvoltage protection (OVP), cycle by cycle current limitation, system output open-loop protection, chip output driver maximum voltage clamp, etc
