TPS63050: soft-start and Ilim0/1 Config

Datasheet has no equation and discription regarding the SS pin config, please help and specify.

The ILIM0/1 pins configs the start-up input DC current?

Datasheet title says 1A switch current, EC table has no specification, I want to know in normal operation how to calculate my current limit threshold based on my operating condition.

Thanks.

  软起动电路比较简单，主要看你期望输出电压上升的时间，一般SS外界电容为1nf~10nf.

 1A最大输出是指降压buck模式时，但是datasheet对其定义确认很不清楚，在规格表中只有boost时的电流限制规格。
