TPS562200: Layout question

Part Number: TPS562200

Hello everyone,

I am working with TPS562200 IC and I have two questions:

1- Where the EN pin is connected to? Inside the datasheet, it is connected to a resistor and then a label but after that, it is not connected to anywhere!?!

2- Can you please have a look at my layout and see if any consideration is required? I have a very small space on my board and this is the best layout that I could get based on datasheet.

Thanks,

Babak

  

Layout:

  • Hi Babak,

    1, It actually depends on your application to connect EN label. You can connect EN to Vin or a logic signal. It's both ok. In datasheet, it's connected to Vin.

    2, I will send you feedback about layout suggestion by email. please send me email. Edwin-zang@ti.com 

    by the way, please send me the bottom layer of the PCB. I want to see the FB and SW line of bottom layer.

    BRs,

    Edwin.
