LM5143: 2phase application for 12V/60A with 2pcs LM5143

Tiger Yeh

Part Number: LM5143

Tool/software:

Hi,

According to datasheet Fig9-10 for single output with multi-phase application, may I check whether it could support 18V~48V input and 12V/60A output?

Suppose it may be okay, but want to double confirm with team.

Thanks and Best regards,

Tiger

Hi Tiger

12V/60A design is possible with 4 phases as shown in attached picture from your post. I would recommend using LM5143DESIGN-CALC Calculation tool | TI.com design calculator. Do send us schematics for review once design is completed.

I hope this helps

Thank you

Regards

Thanks Onkar.

This is one of solution that my customer is studying.

LM5177x parallel mode is also in survey for buck-boost (8V-48V input).

If they do choice LM5143, will submit design to BU for review.

Have a nice day.

Thanks and Best regards,

Tiger
