notes

1. Guaranteed by design and/or analysis. not an in-line test.

2. Dual and triple outputs: The over-current limit will trigger when the sum

of the currents from both dual outputs or both auxiliary outputs (triple)

reaches the maximum rated “total” current of both outputs. Typical

values are stated in the table.

3. An external inhibit interface should be used to pull the inhibit low or

leave it floating. The inhibit pin can be left unconnected if not used.

4. Sinking current required is VIn/3.3kΩ.
