Linear Technology presents a range of micropower monolithic step-down buck converters these are intended for applications that need to increase efficiency at light loads. These devices produce low standby quiescent currents when in burst mode. They can be used in applications such as high voltage power conversion, battery powered, Automotive, distributed power and Industrial power systems.
