UCC28070, 300-W Interleaved PFC Pre-Regulator (Rev. B)
The UCC28070 evaluation module is a 300-W, two phase interleaved, PFC pre-regulator that uses average current mode control techniques to achieve near unity power factor. The pre-regulator was designed to operate off a universal ac line input of 85 V to 265 V and provides a regulated 390-Vdc output. This evaluation module demonstrates TI's interleaved PFC control technology.
