Part Number: TPS2660

Hi

I got two questions from my customer about TPS26600.
Could you tell me the following questions?

1.
I think that NC terminal should be open, but its is connected to RTN terminal in EVM schematic.
Which is correct?

2.
If I want to be enabled TPS26600(not to use SHDN terminal) at all times, should I open it's teminal?

Best regards,
Yokota

    Hello Yokota-San,

    Please find replies below:

    1.

    I think that NC terminal should be open, but its is connected to RTN terminal in EVM schematic.

    Which is correct?

    NC pins can be left open or can be connected to RTN pin.

    2.

    If I want to be enabled TPS26600(not to use SHDN terminal) at all times, should I open it's teminal?

    SHDN pin can be left open. SHDN is pulled up internally.
