Power Factor Controllers
The portfolio of current- and voltage-mode Power Factor Controllers (PFC) from ON Semiconductor includes highly integrated circuits, in step-up, step-down, flyback, or half-bridge topologies, operating in CRM, CCM, CrCM, BCM, or DCM power factor controller modes. They optimize compact, highly efficient, low current power supplies. They offer input brownout, over-current, open-feedback, output over-voltage, and redundant latching over-voltage protections. Applications for these Power Factor Controllers include AC-DC Merchant Power Supply, LCD TV, PDP TV, High-Power Notebook adapters, and Desktop and All-in-One (AiO) PCs.
