LTC3637EMSE#PBF

LTC®3637 is a high efficiency step-down DC/DC regulator with an internal high side power switch that draws only 12μA DC supply current while maintaining a regulated output voltage at no load. This can supply up to 1A 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. Its 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. Additionally, this includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment. Typical applications are industrial control supplies, medical devices, distributed power systems, portable instruments, battery-operated devices, automotive, avionics.
