SLUSDW0B –MAY 2020–REVISED MAY 2020  
UCC28065 Natural Interleaving™ Transition-Mode PFC Controller  
with High Light-Load Efficiency Supporting High-Frequency Switching up-to 800 kHz  
1 Features  
3 Description  
The UCC28065 interleaved PFC controller enables  
transition mode PFC at higher power ratings than  
previously possible. The device uses a Natural  
Interleaving™ technique to maintain a 180-degree  
phase shift. Both channels operate as masters (there  
is no slave channel) synchronized to the same  
frequency. This approach enables faster response  
time, accurate phase shift, and transition mode  
operation for each channel. The device has a burst  
mode function to get high light-load efficiency. Burst  
mode eliminates the need to turn off the PFC during  
light load operation to meet standby power targets,  
eliminating the need for an auxiliary Flyback when  
paired with UCC25640x LLC controller and the  
UCC24612 or UCC24624 synchronous rectifier  
controllers. The increased frequency clamping  
doubles the switching frequency capability compared  
with previous generation devices. The increased  
switching frequency range also allows the design to  
fully utilize the benefits of GaN MOSFETs such as  
LMG3410 and SiC MOSFETs.
