TPS563200: TPS563200 ripple and load transient

Part Number: TPS563200

Hi team,

My customer wants a buck and I recommended TPS653201. But after test, it fails in output voltage and current accuracy as well as line transient. They need a buck that has <2% accuracy. And I wonder if TPS653200 is suitable. The test conditions and results of TPS653201 are attached below. 

The following pictures are waveform of load transient. They need <5% overshoot and undershoot.

Best Regards,

Peter
