ADP5071 can't start when load large capacitors.

Hello everyone,

     As specified in the datasheet, ADP5071 will shutdown if the current exceed the limit. When I use about 100uF capacitor, the start curve is as follow.

     But if I keep increaing the capacitor, it will never work normal. So how can we deal with this?  What's the meaning of "slower soft start"?

     Thanks.
