                                                                                                    LTC3630 is a high efficiency step-down DC/DC converter with internal high side and synchronous power switches that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. It can supply up to 500mA 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. This combination of Burst Mode® operation, integrated power switches, 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.
