  • UCC2895: UCC2895 Soft start, unstable early operation

    TI Thinks Resolved
    Part Number: UCC2895 We encountered a problem, however, that I would like to get some feedback on. We are using the UCC2895 by using the SS/DISB pin for disabling in the following manner: To achieve a more precise output voltage, we are using an external…

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

    Hello, I prefer designing phase shifted full bridge designs in peak current mode control vs voltage mode control. This helps prevent transformer saturation, protects the H Bridge from over current and eliminates the need for a DC blocking capacitor in…

  • UCC2895: Output voltage drops down when power up ( phase shift topology)

    Resolved
    Part Number: UCC2895 Hi Experts; I am currently facing a problem regarding the output voltage. Nearly all test conditions are normal but when I increased output power, up to 3300watt for instance, the output voltage drops approximately 10-20V. In other…

  • UCC2895: dynamically output voltage adjust

    Resolved
    Part Number: UCC2895 Other Parts Discussed in Thread: UCC3895 , Hi team is it possible to adjust the output voltage by injecting a current with a resistor by applying a DAC to the feedback connection of ucc2895/ucc3895? Note ; the controller is on the primary…

    Part Number: UCC2895 Hi Sir, I am testing this controller if i direct turn on the input the controller pulse is getting off and in output voltage ripple is more

  • UCC2895: Not recovered after over current fault

    TI Thinks Resolved
    Part Number: UCC2895 When the output is short-circuited (CH1), the waveforms of SS pin (CH1) and CS pin (CH2) are as follows, CS pin tops to nearly 2V and then returns to 0V. look at the SS pin from high to low but cannot recover. Want to know if there…
