Other Parts Discussed in Thread: LM5175, LM5176, TPS55288

Hello There,

We are designing a new product for automotive applications (like ECUs) that is powered by an input source of 9 to 36 V, and the ambient temperature of 65 degrees Celsius. we need a few regulators for that, which are listed below.

Regulator1: Output = 12 V 5 A; Regulator 2: Output = 5 V 10 A; Regulator 3: 5 V 15 A. We found the LM5175 series 4-switch buck boost converter to be suitable for our application. in that we have a few questions.

The problem with the LM5175 is that it requires more space; our board does not have that much space, hence we need a smaller buck boost controller, so can you please list the available buck boost regulators to satisfy all our needs?

Thanks,
Sakthivel

Hi Sakthi,

Thank you for using E2E forums, regarding your query what package of LM5175 are you using? LM5175 comes in two packages, have you seen the smaller package?

Also, you can have a look at LM5176 https://www.ti.com/product/LM5176

Hi Haroon,

Thanks for your support,

My concern is not only about the IC package the rest of all the discreates as well, but we also don't have that much space to accommodate 4 switches that's why we need a buck boost converter having internal switches satisfying all our needs.

Thanks,

Hi Sakthi,

In that case I would recommend TPS55288 https://www.ti.com/product/TPS55288#product-details it should be able to deliver what you are expecting.
