Hi,

One of my customer is willing to use TI's TPS51200 for their network application.

They ask to TI if there's any problem on their schematic.

Please help us.

    Hello,

    Below are the comments on schematic.

    • Place a 0.1uF cap between REFOUT pin and GND.
    • Change the cap between REFIN and GND from 10nF to 1nF.
    • Add a 100k ohm resistor between PGOOD pin and VIN pin (pin 10)
    • Add at least one more 10uF cap between VLDOIN and GND
    • Add at least one more 10uF cap between VO and GND.

    There are some reference design on datasheet. Please ask customer to follow these reference designs.

    Thanks

    Qian
