Conditions:
R input not connected. For multiple-output models the figures indicated in the table relate to the output, which reacts slowest. All
outputs are resistively loaded. Variation of the input voltage within Vi min Vi max does not influence the values considerably.
Auxiliary Functions
Inhibit
The outputs of the converters may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied between the
inhibit input i and the negative pin of output 1 (Vo1–). In
systems with several converters, this feature can be used, for
example, to control the activation sequence of the converters.
If the inhibit function is not required, connect the inhibit pin 2 to
pin 23 to enable the outputs (active low logic, fail safe). The
response times are specified in table 6.
