The UCC28070A is an extended frequency range derivative of UCC28070, capable of operating at low switching frequencies desired for IGBT power switch based PFC converters in high power applications.
The UCC28070A is capable of operating in frequency range 10 kHz to 300 khz, thus extending the range of operation compared to UCC28070 whose minimum operating frequency was limited to 30 khz. All the other features and benefits of UCC28070 are also available in UCC28070A. The 180 degree out-of-phase interleaved operation generates substantial reduction in input and output ripple currents and conducted EMI filtering becomes easier and less expensive.
