It is an active power factor correction controller in continuous conduction mode, suitable for medium - and high - power switching power supplies. It has built - in high - performance multipliers and dividers. Together with the optimized THD circuit, it improves the PF value of the entire system. It is equipped with comprehensive protection functions, including VCC under - voltage protection (UVLO), system output over - voltage protection (OVP), cycle - by - cycle current limitation, system output open - loop protection, and bus input under - voltage protection.
