1/ Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be
guaranteed to the limits specified.
2/ Applicable to positive and negative outputs.
3/ Output load current must be distributed such that at least 20 percent of the total load current is being provided by one of the
outputs.
4/ Load current split equally between +VOUT and –VOUT
.
5/ Cross regulation is measured with 20 percent rated load on output under test while changing the load on the other output
from 20 percent to 80 percent of rated.
6/ Capacitance load may be any value from 0 to the maximum limit without compromising DC performance.
7/ Load step transition time 10 microseconds.
8/ Recovery time is measured from the initiation of the transient to where VOUT has returned to within 1 percent of its steady
state value at 50 percent load.
9/ Input line step transition time 100 microseconds.
10/ Turn-on delay time from either a step application of input power or a logic low to logic high transition on the enable pin.
