  • TPS7A57EVM-056: LDO_Transient_Response_Results

    Part Number: TPS7A57EVM-056 Other Parts Discussed in Thread: TPS7A57 , TPS54623 In our design we are converting voltages 12V to 3.3V using buck converter(TPS54623) and from 3.3v to 1.8v using LDO (TPS7A57) for the IL- 3A. We have tested the Buck…

  • TPS7A57EVM-056: Power management forum

    Part Number: TPS7A57EVM-056 Other Parts Discussed in Thread: TPS7A57 Hello, We have been using the transient model for the LDO regulator TPS7A57. When we vary the output load current as a pulse (say from 3A to 5A), the model does not seem to reproduce…

  • RE: TPS7A57: Generation of 5V out from 5.5V input without any additional input/bias voltages

    Resolved
    Hi Bivin, If you want to generate 5V from 5.5V using the TPS7A57 then connect the CP_EN pin to VIN and use the internal charge pump instead of BIAS. The BIAS pin can be left floating. I had an EVM (TPS7A57EVM-056) readily available so I quickly confirmed…
