TPS56528: Alternate part with low input voltage

Arumugam Palaniyandi

Part Number: TPS56528

In our project we used TPS56528 to generate the 1.2V / 5A, When we use this part the input voltage Min required 4.5V as per the datasheet.

As per the project change request the input voltage we plan to use 3.3V instead of 5V.

So could you please suggest direct cross part from TI and the input voltage 3.3V and the output voltage is adjustable to able to fix 1.2V. current rating we are OK 3 or 5A .

Hi Arumugam,

what's the maximum input voltage that you required? 17V, right?

Min voltage 2.9 ..Basically we are going to generate from 3.3V input.
