LTC7138EMSE#TRPBF

LTC7138 is a high efficiency step-down DC/DC regulator with internal power switch that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. This device can supply upto 400mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency and for reducing output ripple and component size. The device’s combination of Burst Mode® operation, integrated power switch, low quiescent current, and programmable peak current limit provides high efficiency over a broad range of load currents. It is widely used in application such as industrial control supplies, medical devices, distributed power systems, portable instruments, battery-operated devices, avionics, automotive etc.
