TPS65400: 6A current using parallel connection

RAHUL SHARMA52

Part Number: TPS65400

We have requirement of 6A current in one rail. Can we combine Vout1 & vout 3 to meet 6A current requirement.

Vin = 12V

Vout = 1.8V(Typ) range 1.8V to 1.9V

Programmable output using I2C

Current = 6A Max

Hi,

For TPS65400, only provide below 2 current sharing setup:

1. the Buck1 and Buck2 can share to provide 8A current,

2. the Buck3 and Buck4 can share to provide 4A current.

so it means the Buck1 and Buck3 cannot current sharing.

So it means I can combine buck1 & buck2 for 6A current requirement?

In this case, the programmable output voltage can be done using I2c for Buk1 & buck2 together?
