LTC3638EMSE#PBF

LTC3638 is a high efficiency step-down DC/DC regulator. It can supply upto 250mA 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 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. With its wide input range of 4V to 140V and programmable overvoltage lockout, this device is a robust regulator suited for regulating from a wide variety of power sources. Additionally, it includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment. It is used in application such as industrial control supplies, medical devices, distributed power systems, portable instruments, battery-operated devices, avionics, automotive etc.
