hi all:
1.Can anyone tell me How to select the proper of the compensation's Rz and Cc.
because the Rload always changes .

Rz*Cc = Rload*Cout.

2.What the curve of the output voltage looks like?

Which is the better?
thanks!
 

Seriously not clear on the waveforms. Can you kindly post them in a clearer format? If you mean, whether there should be peaks in the output voltage, then the best thing would be the first one provided there is enough time for the load to get powered up. More importantly, the error in the steady state will determine which model you select.
 

Look at pg. 29 of this document.
