Power factor correction (PFC) controllers
Power factor correction (PFC) controllers with the highest efficiency and lowest THD for your high-voltage applications.
Our PFC controllers offers the highest efficiency, lowest standby power, and superior power factor and current distortion for your switched-mode power supplies (SMPS), which helps you meet challenging standards like the DoE Level-VI and EU CoC Tier-2. From critical conduction mode/transition mode (CRM/TM) to continuous conduction mode (CCM) PFC, we’ve got it all.
New portfolio of PFC controllers for low and medium power designs delivering excellent light load efficiency and low standby power over all load conditions
Industry’s best portfolio of 2-phase TM PFC controllers geared toward medium power for slim profile applications
Competitive portfolio of CCM PFC controllers for medium to high power applications for smaller footprint and easier layout options
Improve the performance of your AC/DC design
The UCC28056, UCC256403, and UCC24624 eliminate the need for an auxiliary flyback by achieving low standby power consumption. Along with other features, such as excellent audible noise performance, we enable you to improve your AC/DC design to do more with less. See how with our reference design and test for yourself on our EVM.
Featured reference designs
The PMP21251 reference design uses UCC28056 CRM/DCM PFC controller and UCC256304 enhanced LLC controller with integrated. driver to provide 12V/10.8A output (continuous, 14.4A peak) from universal AC input.
This reference design is a compact, high efficiency, fast transient, universal input, 12-V DC, 200-W nominal output, AC/DC power supply (PSU) targeted for desktop PCs and gaming adapters.
24V, 480W nominal 720W peak, >93.5% efficient, robust AC/DC industrial power supply reference design
The TIDA-01494 reference design is a compact, high efficiency, 24-V DC, 480-W nominal, 720-W peak output reference design for industrial AC/DC power supplies.
