Other Parts Discussed in Thread: TPS5450,

Hi, TI support Team

I have received inquiries about the differences between the following two products from customers.

TPS5450

TPS5450-Q1

1. Are there any functional differences?

2. It is usually thought that there is a difference in temperature spec, but it is necessary to check whether the content extracted from the datasheet below is accurate.

Which of the parameters in the red box has the better spec?

[TPS5450]

[TPS5450-Q1]

Thanks.

Hi MJ,

1. There is no functional difference between these two parts.

2. for the spec in red box, the smaller the better as the junction has lower temp increase referred to board or case top

Hi, Andy

Thanks for your reply.

Generally, we know that automotive products have better temperature spec than catalog products or industrial products.

As for the product, is there any reason why the temperature spec is not better for the automotive product?

Thanks.

Hi MJ,

This maybe caused by the thermal model correction during thermal metric simulation
