Notes

1. Guaranteed by qualification test and/or analysis. Not an in-line test.

2. For better protection, the current limit function of the main and the

auxiliary sides are linked together. If one output goes to current limit,

the other outputs will be turned off at the same time.

3. The over-current limit will trigger when the sum of the auxiliary

outputs reach 130% (typical value) of the maximum rated “total”

current of both outputs.

4. Tested with inhibit pin pulled to ground.

5. 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.
