  RE: UCC28070: can ucc28070 support 1kHz AC input

  Hi Qiu: We had tested UCC28070EVM at 800Hz, it can work normally but a little worse of PF. If you want to further increase the input frequency to 1Khz, it will further influence the PF and ITHD,and should be normal working. attached is the 800Hz test...

  RE: TINA/Spice/UCC28070EVM: Pins are different then datasheet

  Hi All, It will not be feasible to run a complete PFC model in Spice, hence the average model was provided which does not model all pins. If you need a complete model, we can share a SIMPLIS model, but you will need a SIMPLIS simulator license from...
