Pin No. Pin Symbol Function 1 EN/SYNC Enable and synchronization input. The falling edge synchronizes the internal oscillator. The part is disabled into sleep mode when this pin is brought low for longer than the enable time−out period. 2 ISNS Current sense input. Connect this pin to the source of the external N−MOSFET, through a current−sense res.
include internally−set soft−start, undervoltage lockout, cycle−by−cycle current limiting, hiccup−mode short−circuit protection and thermal shutdown.
Additional features include low quiescent current sleep mode and externally−synchronizable switching frequency.
