LMZ35003: Terminals that are conductive to each other

Shuji Ishiwata

Part Number: LMZ35003

Tool/software:

Hi All,

I have a question about the LMZ35003.
Please tell me about the terminals highlighted in blue below.
Are there any terminals that are conductive with respect to each other?
Please let me know if there are any terminals that are conductive to each other.
For example, DNC terminal pins 2 and 3 are conductive. Also, VIN (pin 26) and SS/TR (pin 28) are conductive. etc.

Best Regards,
Ishiwata

Hi Ishiwata,

Apologies, I am not familiar with the terminology being used. Can you elaborate about what you mean about the conductiveness of the pins? Do you mean the resistance of the pins or the estimated current draw of the pins etc.?

Thank you,

Joshua Austria

Hi Austria,

Thank you for your reply.

Regarding continuity, are there connections between the pins? Or are they shorted? Are they connected via a low resistance?
That's what we're looking for.

Of the terminals shown in blue, are any of them connected internally?

Best Regards,
Ishiwata

Hi Ishiwata,

Sounds good.

For the device connections please refer to the functional block diagram present in the datasheet.

I have included it below for your inconvenience, this should give you better insight on the internal connections of the part.

Thank you,

Hello Austria,

Thanks for your reply.

Are the DNC terminals not connected internally?
Are they left unconnected independently?

Best Regards,
Ishiwata

Hi Shuji,

The DNC pins (2, 3, and 25) are connected to internal circuitry yes. They must each be soldered to an isolated pad and cannot be connected to each other per Table 2 of the datasheet.

Thank you,

Joshua Austria
