  • TPS561208: Power multiplexing best practice

    Resolved
    Part Number: TPS561208 Hello, We use a TPS561208 to convert 12V power supply into 5V output and further down to 3.3V ouput with LDO to power the MCU. At the same time, we have another power source coming from USB and the requirement is to power the…

  • RE: TPS561208: TPS561208

    Hi Edwin, So expected behaviour is higher switch node ringing with higher load, right ? And I'm guessing the ringing would be similar between TPS561201 and TPS561208 even with the pulse skipping low load region in TPS561201 . Also would you recommend operating…

  • TPS561208: Switching layout guidelines

    TI Thinks Resolved
    Part Number: TPS561208 Other Parts Discussed in Thread: TPS563202EVM Hi, on the SPEC in section 10.1 it is recommended not to route the switching under the device. can help to elaborate more why it is not recommended? in my design i've routed it beneath…

  • RE: TPS561208: TPS561208 Output Voltage Problem

    Hi, Only TPS561208 is available in my circuit. I mean there is no other unit. I'm just trying this circuit. Maybe the TPS561208 IC is broken, so I changed it and tried it again, if you mean it. The result is always the same.

  • TPS561208: Catastrophic failure

    Resolved
    Part Number: TPS561208 I have a unit that appeared to be sensitive to input ripple voltage and would catastrophically literally burn up. I have been investigating to find a root cause of why that might occur. I moved on to another unit in the design and…
