  • RE: UCC2895: Could I have an unencrypted SPICE model for UCC2895/UCC3895?

    Hello, I learned from the data sheet of ucc3895 that ucc3895 can work in current mode or voltage mode. In current mode, the RAMP pin is connected to the CS pin. And in voltage mode, The RAMP pin is connected to the signal at CT. I want ucc3895 to work in voltage…

  • RE: UCC3895: How to avoid run into CS = 2V ~ 2.5V

    Hello, I reviewed your schematic and waveforms. I reviewed your schematic and the design seems to be setup for some kind of half bridge and not a full bridge. The UCC3895 is not designed for this configuration. This is most likely what is causing your…
