Undervoltage Protection If the voltage detected on the FB pin falls 14% below the internal reference voltage and the overcurrent condition flag is LOW, then the regulator will be shut down immediately under an undervoltage fault condition. An undervoltage fault ...

... The switching components should be placed close to the ISL8540 first. Minimize the length of the connections between the input capacitors, C output capacitors as short as possible. NOTE recommended that any applications with input voltage greater than 30VDC should be polymer coated to meet Intersil’s IPC-2221 creepage and clearance specification ...
