  • TPS53513: Soft Start Time Maximum

    Resolved
    Part Number: TPS53513 Do we have any guidance on the distribution of soft-start time for this device (from the rise of EN)? Esp. the Max time. We have a system that requires the device to reach regulation within 2.2msec and need to know if this device…

  • TPS53513: OCP threshold when TRIP pin is shorted to GND or floated while running

    Resolved
    Part Number: TPS53513 Hi, We are assessing the failure mode of the converter design. We would like to know if OCP threshold will change when TRIP pin is shorted to GND or floated while the converter is running. From the datasheet I'm assuming the following…

  • TPS53513: Enable function delay

    Resolved
    Part Number: TPS53513 While testing start-up sequence in our design, I observed about 1ms of delay between enable and soft-start. A diagram in datasheet shows that the delay is about 400 µs. However there is also a start-up sequence waveform in datasheet…

  • TPS53513: noise suppression methods

    Resolved
    Part Number: TPS53513 Hello. I'm now trying to make 0.9V using TPS53513. So I have a few questions. It generates 0.9V from 12V, but 12V has switching noise of about 100kHz. Is the only way to reduce this noise is to filter the input stage of the TPS53513…

  • TPS53513: Abnormal output

    TI Thinks Resolved
    Part Number: TPS53513 Hi All, A customer using TPS53513 reported an abnormal output voltage. I want to send a waveform, but I haven't got permission from the customer, so I want to share it via private message or email. We look forward to your support…

  • TPS53513: Vref out of spec

    TI Thinks Resolved
    Part Number: TPS53513 Hello, We've been using the TPS53513 on one of our product for a couple of years without any problem but on the last batch Vout happens to be out of spec. When the board is idle (low power), we measure FB at 0.6247 V and 0.6272…

  • RE: TPS53513: IV characteristic evaluation between SW and PGND

    Peter James Miller Thank you for your polite answer. I understand that both characteristics appear when no power is entered. When I checked with the customer, I found that it was a sample that was confirmed to work with the application. I used to say it…
