PFC Converter Controller - Suzhou Jiyuan Electronic Technology Co., Ltd.

PFC Converter Controller

PFC Controller family adopts boundary conduction mode, which is suitable for small and middle power applications. It achieves high PFC and minimum THD of AC input current. The extremely low start-up current, quiescent current, and disable function reduces power consumption, allowing it to be used in low standby power applications.
