UCC28064A Transition-Mode PFC Controller
Texas Instruments UCC28064A Transition-Mode PFC Controller has higher power ratings than previously possible. The device uses a Natural Interleaving™ technique. Both channels operate as masters (there is no slave channel) synchronized to the same frequency. This approach enables faster response time, excellent phase-to-phase on-time matching, 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. Burst mode eliminates the need for an auxiliary flyback converter when paired with UCC25630x LLC controller and the UCC24624 synchronous rectifier controller.
