TPS536C7: Looking for Buck controller IC/IC's required for 0.82V@60A,0.82V@25A,0.82V@30A designs

Part Number: TPS536C7

Tool/software:

Hi, 
In our new design, we are planning a power stage which has below requirements.
Vin 12V+/- 8%
All vouts tol:- ±2.5%
Vout1 - 0.82V@60A (Core), tol:- ±2.5%
Vout2 - 0.82V@25A (IO1)
Vout3 - 0.82V @ 30A (IO2)
Vout1 has SR of 2A/uS, and single transient of 25A/1ms when chip comes out of RESET (not required to be in ±2.5%)
Vout2,3 are not much stringent.
Digital power measurements by IC is good to have,
I2C configuration is good to have.
 
Can you suggest Buck controller solution on this.

    Hi Koppa,

    Thanks for reaching out.

    Looking at your requirements, since you have 3 rails, you will need 2 controllers because we have only 2 channel devices. You can use 1 controller for Vout 2 and Vout 3 and 1 controller for the Vout 1.

    Since the currents are not much, so you wont need many phases.

    I think TPS53647 would work well and it seems like it would be a great fit for your application when it's paired with one of TI's Smart Powerstages. 

    Let me know if you have further questions.

    Thanks & regards,

    Abhishek
