Power factor correction (PFC) controllers
PFC controllers with the highest efficiency and lowest THD for high-voltage applications
Browse by category
Select by type
Single-phase transition mode (TM)
Use in low- and medium-power designs to deliver excellent light-load efficiency and low-power over all load conditions.
Single-phase critical conduction mode (CCM)
Use in medium- to high-power applications for a smaller footprint and easier layout options.
Power density
Minimize your solution size while maximizing your efficiency
Our PFC controllers offer higher switching frequency ranges for minimizing inductor size. Additionally, many solutions leverage burst mode to provide high light-load efficiency and eliminate the auxiliary flyback when paired with inductor-inductor-capacitor (LLC) or synchronous rectifier (SR) controllers. Our interleaved controllers enable multiphase design and parallelization for scalability.

Enable high efficiency and power density with our low-cost, small-footprint, sophisticated PFC solutions
In consumer electronic AC/DC power supplies, cost is often a primary design constraint. Our analog PFC controllers help you minimize common design and development costs ultimately improving your cost to market.
Benefits:
- A high switching frequency reduces inductor footprint and system bill of materials.
- Transitional mode operation minimizes power loss across the load with silicon field-effect transistors.
- Easier system design requires no firmware development.

Achieve low-profile designs with high power density, high efficiency and low total harmonic distortion (iTHD) with our PFC controllers
As TVs increase in size while decreasing in width, our interleaved two-phase power factor correction controllers maximize power density and efficiency while minimizing standby power.
Benefits:
- Switching frequencies as high as 800 kHz enable a smaller inductor footprint (especially height).
- An interleaved design reduces the input current ripple and minimizes electromagnetic interference and iTHD.
- Transitional mode operation minimizes power loss across the load with silicon field-effect transistors.
