7.3.17 Soft-Stop Off

The Soft-Start Off (SSOFF) pin gives additional flexibility by allowing the power converter to be configured for

hard-stop during line UVLO and hiccup mode condition. If the SS OFF pin is pulled up to the 5-V REF pin, the

power converter hard-stops in any fault condition. Hard-stop drives each control output to a low state

immediately. Refer to Table 1 for more details.
