TPS26600-02EVM: Latch-off mode at 0.2A limit

Hi,

our customer tested Latch-off mode various current limit.

The customer complains that it will be Auto-retry only in the 0.2 A limit. Latch-off operation is performed with other current limit.

Why do you know that it will be Auto-retry only at 0.2 A?  Please let me know if you need confirmation.

This test follows the table below.  (http://www.tij.co.jp/jp/lit/ug/slvuav3a/slvuav3a.pdf)

Table 4 ,Page 4

                         3-4 position sets 1.5 A      ... OK
