PFC Controllers
Power Factor Correction Controllers
Renesas' power factor correction (PFC) controller family uses boost topology and are suitable for AC/DC power systems, up to 2kW and over the universal line input. These PFC controller IC's operate in continuous conduction mode (CCM), and the small external components result in a low cost design without sacrificing performance.
Use the following table to identify which Renesas PFC controller will best meet the needs of your next project:
