Not production tested.
Soft-start time is measured with respect to the number of cycles on LX.
This is a metal migration limit. Maximum output current may be limited by thermal capability to a lower value than this.
Specifications from 0 ° C to -40 ° C are guaranteed by design, not production tested.
