Switching Regulator (ISR) designed to
meet the on-board power conversion
needs of battery powered or other equip­ment requiring high efficiency and
small size. This high performance ISR
offers a unique combination of features
combining 87% typical efficiency with
open-collector on/off control and ad­justable output voltage.

Quiescent current in the shutdown

mode is typically less than 100µA.
