Hi Sir,

TPS61170 is not fit for this application. it can't support such high output power.

Suggest you use a controller like LM3478/LM3481, or buck-boost controller like LM5175. And you can open a new post if you are insterested in them. The related person will answer your question.

Dear Halen,

LM3478 / LM3481 can I use for 10A application because In data sheet shows its 1A. Kindly suggest 10A current driver with SEPIC Topology driver.

I checked in EVM guide its also shows 3A.

Below is EVM guide link :

Thank you,

1A is diver capability which is used to drive the external MOSFET. the current capability of the external MOSFET can be much higher than 1A, I think can be 10-20A.

Suggest you open a new post on LM3478/81, the person in charge of these products will answer your question more precisely!
