Event Description

The totem pole PFC topology removes the need for an input diode bridge, reducing power losses and enabling high density solutions. onsemi’s multi-mode totem pole PFC allows high efficiency under a wide range of load conditions. Combining this with the upcoming integrated driver GaN products and onsemi’s fast current-mode LLC controller enables an ultra-high density 300W power supply which will be reviewed in our webinar.

Key Takeaways

  • Review how compact and efficient 300W power supply solution is enabled by onsemi multi-mode totem pole power factor correction controller and high speed LLC controller working together with onsemi driver GaN solution.
