F XAIS3531 DESIGN CONSIDERATIONS Over Current Protection The converter is protected from short circuit and over current conditions. Upon sensing a short circuit or an over current condition the converter will immediately shut off, and after a short delay try to restart. This is called a ‘hiccup’ mode and this mode will persist until the short circuit or over current condition is removed. Over Temperature Protection The converter is NOT protected from over temperature conditions. Exceeding the maximum rated case temperature may cause permanent damage to the unit. Fusing The input to the converter is protected with a UL R/C fuse. This fuse is NOT user replaceable.
