Description

The UCC28070 is an advanced power factor. Interleaved Average Current- Mode PWM correction device that integrates two pulse-width. Control with Inherent of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. This power converter achieves PFC with the use of the UCC28070 interleaved PFC The UCC28070 evaluation module is a 300-W, two phase interleaved, PFC The pre-regulator uses the UCC28070 PFC interleaved controller to shape the 1. Bridgeless PFC. Application Report. SLUA517 JULY 2009. UCC28070 Implement Bridgeless Power Factor Correction. (PFC) Pre-Regulator Design. The UCC28070 device also contains a variety of protection features including output-overVoltage detection, programmable peak-Current limit, undervoltage
