In this seminar, you will discover how to implement a compact, efficient, high-performance PFC-LLC power supply in this seminar. Our focus: a 1 kW, Universal Input, 50 V Output Power Supply. Leveraging onsemi’s NCP1681 Totem pole PFC controller and NCL30159 LLC controller, it delivers high PF and low THD. Through the integration of innovative topologies and the utilization of GaN switches, it ensure superior efficiency in both CC and CV load modes, with a deep SKIP function, making it ideal also for high-power, low profile LED drivers.
