TLV62085: About Internal Structure.

Hi Kengo,

Can you please share the reason why did the customer do the X-ray? Was there any issue that customer faced? Please let me know in order to be able to help you further.

Thanks!

Best regards

Hi Sneha,
Thank you for your reply.
My customer is wondering if this adhesion will affect the long-term reliability.
Is there any possibility of short circuit between SW and GND inside?

Sincerely.
Kengo.

Hi Kengo,

Thanks for the reply. 

I have some additional  questions:

1) Are any of the pins of the device are shorted to each other? For ex: Vin-Sw pin or Sw pin- GND pin? 

2) Does the HS FET/LS FET have large RDSon? 

3) Are you able to get the body diode voltage across the Sw- Vin and GND- SW? Please Let me know.

Meanwhile, In regard to the x-ray. I will contact the concerned team. 

Thanks! 

Best regards

Hi Sneha,

Thank you for your reply.

Resistance cannot be measured because it is not implemented.

I will wait for the contact from the related team who can judge from the X-ray.

Sincerely.
Kengo.

Hi Kengo,

Could you please elaborate what do you mean by " resistance cannot be measured because it is not implemented"? 

Can you share the LTC information in order to check whether there is a risk in those parts? And are these pictures after soldering or the units are freshly out of T/R? 

Thanks!

Best regards

Sneha

Hi Sneha,

I'll check LTC information.
These pictures before soldering.
So, we can not measure resistance for devices.

Sincerely.
Kengo.
