TPS40303: Powering an Altera/Intel FPGA for efficiency purpose - is it safe

Part Number: TPS40303


I need to generate a 0.9V from a 12V input (17A max) and the design is highly constraint in efficiency.

I did look at the recommended TI parts for Altera/Intel but I need an efficiency above 90%. Which I achieved with a TPS40303 part in WeBench, selecting efficiency as the main criteria.

At start-up, the overshoot is around 0.950V where the input is between 0.87V and 0.93V. And there is a similar issue with the load transient response.

Is there anything I could do to lessen the overshoot ?
