TPS61230: TPS61230 Transient

Part Number: TPS61230

Hi Experts, 

I use TSP62130 to design a circuit, 

Input : 4.75~5.25V

Output : 5.1V

Iout Max : 2A

When I test the performance of transient, I add a Cff 27pF to improve the transient, I = 0.5~2A @ 1A/uS

But it still over my design spec(4.895~5.355), and increase the capacitance of cff, the result doesn't change.

Also I add more capacitor on otput and input, it no effect.

Is there any other way, that we could try to improve the transient ?

C100 = 27pF ( Please ignore the value of the PIC showed.)
