UCC28070 Evaluation module


Order now


The UCC28070 evaluation module is a 300W, 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 85V to 265V and provides a regulated 390V dc output. This evaluation module demonstrates TI's interleaved PFC control technology.
