TPS65131-Q1: TPS65131-Q1

Part Number: TPS65131-Q1

Hi,

We are using part TPS65131RGER in our design. 

Input = 3.3V

o/p +15 and -15 , both loads 75mA

How we can determine the power across the device? 

We need to calculate temperature rise of the part.

Regards,

AVM

    Hi Amod,

    I'll search if there is a calculation tool for TPS65131-Q1.

    And I think if you concern about thermal issue, it's better to run a thermal test with your board and observe IC temperature with a thermal imager.

    Hi Patrick,

    Before going to board test we are doing stress analysis for our design. In that regard I would like to know how we can determine power across device. There is no equation provided for it. 

    In linear technology chips these equations are provided.

    Regards,

    Hi Amod,

    Unfortunately we don't have calculation tool with TPS65131-Q1 for now.

    Compared with linear devices, TPS65131-Q1 used additional DC-DC components such as inductor and diode, which could also lead to power loss, so it's more difficult to calculate the power across the chips accurately.
